I have a stock 2014 GS. I want to improve the HP without voiding the warranty. I know I can do an air intake, but what else can I do?

Thanks

There is no practical way to get enough hp on this car to feel any tangible difference.

Seen a lot posted about this topic and a lot of debate. Intake and exhaust are the typical mods for HP gains, but they are minimal.

A combination of intake, exhaust, and reducing weight (lighter wheels/tires, empty out your trunk) wherever possible may make the car feel lighter on its feet...

We're all waiting for a real bump in HP from the factory for the next Gen 5GS...

Will intake on its own do much? Maybe even change the sound if nothing else.

Have a trusted mechanic in my family that attests to the following: Most of the time, an intake is going to give you more or less a few HP that won't be usable/noticeable. The stock 4GS intake has a sound generator that pumps "intake sound" into the cabin that you will likely lose if you replace the stock intake on the 4GS. Here are some great threads on the 4GS and the intake question:

Hold down the traction control button while stopped for 10 seconds or so. Once all the nannies are disabled the car gets much quicker. You won't believe how much power is trapped under the TCS and stability systems.

Do this at your own risk though. The car won't do anything to save you if you get it sideways in this configuration. One press of the button will turn everything back on.

You will not get any real HP gain without a ECU tune of course. As stated multiple times you can gain minimal HP from intake and exhaust. If you don't want to void your warranty, those are your only real two options.

In the future (pray to god) STILLEN may be able to release a Supercharger that can add 6-7 psi - 100 wHP???? again pray!

I have intake, exhaust and headers. With the headers alone the car is quicker but a super charger is the way to go or u can be like me and order 100 shot nos.

Chip it and supercharge it.
