2014 Infiniti Q50 Modding: The Best First Upgrades for New Owners
There is a specific thrill that comes with walking up to a 2014 Infiniti Q50 in the driveway that you just brought home—the curves are right, the exhaust note is promising, but somewhere in the back of your mind, you are already thinking: “Okay, what’s the first thing I change?”
Congratulations. You just bought one of the most underrated platforms in the modern JDM scene. Whether you picked up a 3.7-liter V6 from the G37 days or scored a 3.0-liter twin-turbo VR30, you are sitting on a car with massive potential. But here is the thing about buying a ten-year-old luxury sports sedan: it is a blank canvas, and the options are overwhelming.
Do you throw a tune on it immediately? Lower it? Change the wheels? Delete the chrome? The difference between a successful build and a money pit is knowing where to start. Let’s talk about the best first upgrades for the 2014 Infiniti Q50—the ones that give you the biggest smile per dollar and set the foundation for everything else.
TL;DR
The best first mods for a 2014 Infiniti Q50 focus on reliability, handling, and personalization. Start with a heat exchanger upgrade if you have the 3.0t VR30 engine—the stock unit heat soaks fast . Then, address the shifter feel with a replacement like the Z1 Billet Aluminum Shift Knob to eliminate the rubbery factory slop . Aesthetic mods like a chrome delete and lowering springs provide the biggest visual impact for under $500 . Finally, a tune (via EcuTek) unlocks hidden horsepower, but only after you’ve addressed the cooling .
Key Takeaways
- Cooling First (VR30): The stock heat exchanger is inadequate. Upgrading it prevents power loss after one pull .
- Shifter Feel (3.7): The 7-speed automatic’s shifter feels vague. A weighted shift knob transforms the daily driving experience .
- Visual Impact: A vinyl chrome delete and quality lowering springs change the entire personality of the car for minimal cost .
- Maintenance is a Mod: On a 2014 model, refreshing fluids and bushings is the foundation of reliability .
- Tune Last: Get the hardware right, then unlock the software. EcuTek tuning offers massive gains but requires a solid baseline .
Know Your Platform: 3.7 vs 3.0
Before you buy anything, you have to know what you are working with. The 2014 Infiniti Q50 came in two main flavors in the US:
- Q50 3.7 (VQ37VHR): This is the carryover engine from the G37. It is naturally aspirated, makes 330 horsepower, and is known for being bulletproof. It sounds incredible with an exhaust, but power gains are expensive.
- Q50 Hybrid (VQ35HR + Electric): Fast, but heavy. Modding these is tricky due to the electric motor integration.
- Q50 3.0t (VR30DDTT – later years): While the 3.0t didn’t arrive until 2016, many owners buy 2014s to eventually swap or compare. If you have a 2014, you likely have the 3.7.
This guide covers both, but we will specify which mods apply to which engine.
The “Must-Do” Reliability Upgrades (3.7 and 3.0)
Fluids, Filters, and Bushings
This isn’t glamorous, but it is essential. Your 2014 Q50 is at least a decade old. Rubber degrades. Fluids break down.
- Transmission Fluid: The 7-speed automatic (RE7R01A) is generally robust, but if the fluid has never been changed, do a drain and fill (not a power flush) .
- Differential Fluid: Easy to do and often overlooked.
- Coolant: The VQ37 runs hot. Fresh coolant is cheap insurance.
- Serpentine Belt: Check for cracks. It is a wear item that leaves you stranded if it snaps.
The VQ37VHR engine is known for its timing chain, not a belt. If you hear a rattle on startup, have the timing chain tensioners checked .
The “Gallery Gasket” Warning (VQ37)
If you have the 3.7, there is one big one: the oil gallery gasket. Early VQ37 engines (including some 2014s) had a paper gasket that fails, leading to a loss of oil pressure and catastrophic engine failure . If you don’t have service records showing this was replaced with the updated metal gasket, consider this a preventative maintenance item. It is expensive, but less expensive than a new engine.
Heat Exchanger (VR30 – Future-Proofing)
If you eventually plan to swap in a 3.0t or if you are reading this for a later model, the heat exchanger is the #1 mod. The stock unit is tiny. After one or two hard pulls, the intake air temps spike, and the ECU pulls timing. An aftermarket heat exchanger (like from AMS or Z1) acts as a larger radiator for your intercooler system, keeping power consistent .
The “Feel” Upgrades: Connecting You to the Road
The Z1 Billet Aluminum Shift Knob
Here is a mod that costs under $200 and changes your experience every single time you drive. The stock shift knob on the 2014 Q50 is… fine. But it is light, and the shift action feels a little rubbery.
Z1 Motorsports makes a billet aluminum shift knob that screws directly onto the factory lever (for automatic cars, it fits over the lever and secures with set screws). It is heavier, which gives the shift mechanism a more positive, mechanical feel. It looks like it belongs in a race car and transforms the interior aesthetic instantly .
- Price: ~$140
- Installation: 5 minutes.
- Best For: All Q50s (3.7 and 3.0t).
Weighted Shift Knob (Manual)
If you somehow have one of the rare 2014 Q50s with the 6-speed manual (they exist, but are hard to find), a weighted shift knob is still the best first mod. It reduces the notchiness and makes shifts smoother.
Solid Shifter Base Bushings
For manual cars, or for those who want even more precision from the automatic’s shifter, replacing the rubber bushings at the base of the shifter with solid aluminum ones removes all the slop. It makes every shift feel like you are moving a precision instrument instead of a toy.
The “Looks” Upgrades: Changing the Car’s Personality
Chrome Delete Vinyl Wrap
The 2014 Q50 came from the factory with a lot of chrome—around the windows, on the grille, and on the trunk. On a modern car, that chrome dates it instantly. A chrome delete is the single highest-impact visual mod for the money.
You can buy pre-cut kits for the window trim for around $50-$100. Wrapping the grille surround is a bit trickier. If you are patient, you can DIY it with a heat gun and a weekend. If not, a professional wrap shop will charge $300-$500 .
- Vinyl to buy: 3M 2080 or Avery Dennison gloss black.
- Pro tip: Clean the chrome with alcohol and use a “squeegee” to avoid bubbles.
Lowering Springs
The 2014 Q50 sits a little high from the factory. It looks like a sport sedan with a hint of off-road capability. Closing that wheel gap transforms the stance.
Lowering springs (like Eibach Pro-Kit or Swift) are the budget-friendly entry point. They lower the car about 1 to 1.5 inches, improve handling by lowering the center of gravity, and cost around $250-$400 . The ride quality remains close to stock.
- Warning: If your stock shocks have 100,000 miles on them, lowering springs will finish them off quickly. Be prepared to replace struts soon after.
Wheel Spacers
If you aren’t ready to buy new wheels, wheel spacers (20mm front / 25mm rear is a popular fitment) push the stock wheels flush with the fenders. It fills out the wheel wells and makes the car look aggressively planted for under $200 .
- Safety: Buy hub-centric spacers from a reputable brand (like Garageline or Z1). Cheap spacers vibrate.
The “Performance” Upgrades: Making Power
Cat-Back Exhaust (VQ37)
The VQ37 engine has a fantastic growl, but the stock exhaust muffles it too much. A cat-back exhaust is the best way to wake it up.
- Options: Stillen, Injen, Fast Intentions, Tanabe.
- Sound: Look for “dual” or “single” exit based on your preference. Listen to YouTube clips. The VQ sounds raspy with some exhausts; others deepen the tone.
- Gains: Minimal horsepower (maybe 5-10 hp), but the smiles per gallon are massive.
Intakes (VQ37)
Cold air intakes on the VQ37 are more for sound than huge power. They let you hear the intake suction, which is addictive. A quality intake (like Stillen or Z1) combined with a tune can yield some gains, but on a stock tune, they are mainly for induction noise.
EcuTek Tune (The Big One)
When you are ready for real power, you need a tune. For the 2014 Q50 3.7, an EcuTek tune (usually done by a remote tuner like AdminTuning or Z1) can unlock an extra 20-30 horsepower just from optimizing the fuel and timing maps .
- For 3.0t owners: This is where you get 100+ horsepower, but you absolutely need the heat exchanger first.
- Process: You buy an EcuTek cable, flash a base map, data log, send logs to the tuner, and get revisions.
Upgrades Comparison: Bang For Your Buck
To help you decide where to spend your first $1,000, here is how the most popular upgrades stack up against each other.
| Mod Category | Best For | DIY Difficulty | Price Range | Smiles Per Dollar |
|---|---|---|---|---|
| Z1 Billet Shift Knob | Daily driver feel | Easy (5 min) | $140 | 10/10 |
| Chrome Delete (Vinyl) | Exterior modernization | Moderate | $50 – $500 | 9/10 |
| Lowering Springs | Stance and handling | Moderate/Hard | $250 – $400 | 8/10 |
| Cat-Back Exhaust | Sound and smiles | Moderate | $800 – $1,500 | 8/10 |
| Wheel Spacers | Flush fitment | Easy | $150 – $250 | 7/10 |
| Heat Exchanger (VR30) | Preventing power loss | Moderate | $700 – $1,000 | 10/10 (for 3.0t) |
| EcuTek Tune (3.7) | Real horsepower | Easy (flash) | $600 – $900 | 9/10 |
Always secure any new parts properly. A loose wheel spacer or a poorly aligned exhaust can cause damage at highway speeds.
FAQ: Your 2014 Infiniti Q50 Modding Questions Answered
What is the best first mod for a 2014 Q50 3.7?
The Z1 Billet Aluminum Shift Knob. It costs very little, takes five minutes to install, and makes the car feel more connected and sporty every single time you drive .
Is it safe to lower my Q50 on stock shocks?
Yes, but with a caveat. Lowering springs will work with stock shocks, but if your shocks have high mileage (over 80k), they will wear out faster. Budget for new shocks in the near future .
Can I tune my 2014 Q50 3.7?
Absolutely. The VQ37 responds well to EcuTek tuning. You can expect gains of 20-30 horsepower at the wheels with a proper tune from a reputable remote tuner .
How much does a chrome delete cost?
If you do it yourself with a pre-cut kit, it can cost as little as $50-$100. If you have a professional shop do it, expect to pay $300-$500 for the window trim and grille .
What is the oil gallery gasket issue?
On early VQ37VHR engines (including some 2014s), a paper gasket inside the engine can fail, causing a loss of oil pressure and potential engine failure. Replacing it with an updated metal gasket is a preventative maintenance task .
Will a cat-back exhaust void my warranty?
On a 2014, the factory warranty is long gone. On a newer car, a cat-back exhaust generally does not void the warranty unless it directly causes a problem (which is rare) .
What should I do first, tune or exhaust?
For the VQ37, do the exhaust first. It makes the car more fun to drive while you save up for the tune. For the VR30 (if you upgrade later), do the heat exchanger first, then the tune .
Are wheel spacers safe?
Yes, if you buy hub-centric spacers from a reputable brand. They center the wheel on the hub properly, preventing vibrations. Cheap “universal” spacers that just bolt on are dangerous .
The Final Verdict: Your Build, Your Way
The 2014 Infiniti Q50 is a fantastic platform because it rewards smart choices. You don’t need to spend $10,000 overnight to fall in love with the car again.
Start with the little things: order that Z1 shift knob and feel the difference. Spend a weekend with a heat gun and some vinyl wrapping the chrome. Save up for a set of lowering springs to give it that planted stance. Then, when the car looks and feels like yours, start chasing horsepower.
The beauty of the Q50 community is that parts are plentiful and the knowledge is shared. Take your time, do it right, and enjoy the process of turning your 2014 Q50 into something uniquely yours.
