Cold air intakes are among the most tempting G37 coupe mods out there. The plenum is a part of your intake manifold. Plenum spacers are gasket-like metal structures which when fitted, increase the volume of air in the plenum chamber. This helps your engine to draw more air and to reduce heat soak. Plenum spacers are considered to be one of the most effective bolt-on modifications for many cars.
It is important to note that it affects every car in a different way. Interestingly, plenum spacers are an extremely rare G37 mod. However, you can still find aftermarket parts that allow your intake manifold to draw more air. Some of these include:. Exhaust gases are thrown out of your engine through a complex assembly of pipes. The faster the exhaust gas leaves, the more power your car puts out. Performance aside, the first thing that comes to mind when we talk about exhaust system upgrades is the sound.
For most of us, good exhaust note is like music. If you find yourself turning your stereo off just to let some of that sweet exhaust sound into your cabin, exhaust mods are for you. The G37 sounds fantastic even when stock.
Aftermarket performance exhausts make this car sound even better! Headers are the first component of your exhaust assembly. By installing aftermarket headers, you can speed up the process and efficiency of the exhaust release. This works really well with a cold air intake and plenum upgrades. A catalytic converter is an exhaust emission control device that reduces the toxic gases and pollutants in your exhaust gas. It is mandated by law to have one installed in every street driven car.
Deleting the catalytic converter is a tempting option and for good reason. You get more power, better fuel economy, more fuel options, and an insane exhaust note. This can be achieved with the use of test pipes. High-flow catalytic converters provide some of these benefits. Straight-piping your G37 will significantly change the way it drives. Without any restrictions in your exhaust, the engine will breathe a lot better.
This can increase power output and improve fuel efficiency. The y-pipe is what connects your exhaust headers to the catalytic converter. Aftermarket y-pipes help to reduce scavenging which speeds up the release of exhaust gases. One of the best things about installing aftermarket y-pipes is the improved exhaust note.
The most popular G37 y-pipes are from:. This system replaces all the exhaust components that are fitted beyond the catalytic converter. These include the muffler and tailpipe. With a cat-back exhaust system in place, you can either retain your stock catalytic converter or replace it with a high-flow unit. And more heat calls for an upgraded cooling system. The factory cooling system on your G37 is designed to work with stock components only.
Any performance modifications especially forced induction will require you to upgrade your cooling system.
An abnormal increase in engine heat levels without proper cooling can make your G37 less reliable. High-performance radiators are a must-have if your G37 is boosted or has a modified engine. If you live in an area that sees high temperatures throughout the year, getting an aftermarket radiator is a good idea.
Engine oil degrades faster when exposed to a lot of heat. As it gets old, the lubricating molecules in the oil start breaking apart. This causes the oil to lose its lubrication quality which increases friction in your engine. An oil cooler is like a separate radiator exclusively for cooling your engine oil.
This helps to maintain the quality of the oil for a longer time. Every modern car comes with an electronic control unit ECU that controls vital functions like fuel injection, valve timing, ABS and even traction in some cases.
When you make performance upgrades of any kind, it is important to let your ECU know. No matter how athletic you are, a m sprint wearing a pair of flip flops is going to be slower and more difficult than if you wore running shoes.
This applies to everything that generates power; especially cars. Cosmetic mods? The answer is always handling. Preparing your car for the performance upgrades it will likely receive in the future is a great idea.
If you really want to make your G37 feel more sporty, invest in handling mods like tires, sway bars, coilovers, etc.
The way your G37 rides and feels while maneuvering, heavily depends on how your suspension is tuned. It may be subtle, but it does make your car look meaner. Pro tip: Upgrading to coilovers and aftermarket sway bars will instantly transform the way your G37 handles.
With coilovers, the spring and damper are combined into one unit. Coilovers work perfectly out of the box. Coilovers have multiple levels of adjustability. This allows you to tune your suspension the way you want. Just like coilovers, lowering springs are ideal if you want to drop your ride height and improve weight transfer. The V is also available in matte black and hyper silver finishes — coordinating your wheel color to compliment or contrast your paint will help your G look its best.
Avant Garde Wheels is another stellar wheel option for the G37, offering dozens of styles, ranging from the Avant Garde M above with its handsome clean mesh design…. The harder lines of the Nurburgring in Matte Gunmetal help create a more aggressive dynamic. The side profile on these is fantastic, as you can see. Need help getting the right fitment for your G?

One of the easiest way to drop your G37 is with a set of lowering springs, and one of the most trusted brands for lowering springs is Eibach.
Offering a 1. Balancing comfort while still offering much improved handling performance and eliminating the nasty stock wheelgap so that your G37 actually looks like a sportscar rather than bloated.
The difference in appearance is amazing. On top of that, if you factor in the cost of replacing the shock absorbers when you do the springs, a set of coilovers is actually a surprisingly economical option. Since coilovers replace both the shock and the spring together, as a paired unit, coilovers perform better and often ride better than factory shocks with lowering springs.
One of the coilover options available for G37 Suspension are the Tanabe Sustec Pro Coilovers for Infiniti G37 , which solidly eliminates the nasty excessive wheelgap, and sharpens the handling performance of the G even further with sport tuned valving and a lower center of gravity. Not to mention, the stance looks amazing with a great set of wheels. If you live in a snowbelt state and want to get low, a set of KW Coilovers for Infiniti G37 are a great option, offering a corrosion-resistant stainless steel shock body and the quality components KW is known for.

You can see how the KWs fit into the front suspension of your G. In the rear, as with most coilover setups, is an adjustable perch rear spring. Check out that stance on the KW Coilovers. For air suspension, we offer AirRex Air Suspension for Infiniti , which offers digital ride height control to give you on-the-fly ride height adjustability.
