I am a fairly new owner of a 2019 Grand Sport. I am considering my 1st performance mods and am looking for recommendations THAT WILL NOT VOID WARRANTY. Cold air intake paired with exhaust upgrade? Suggestions?

 

I would get some custom Lloyds floor mats, although they're not "performance" mods, they are a comfort item you'll notice every time you drive and they also dampen some of the interior noise.

 

Welcome to you both to the forum.
Probably the best way to determine if it voids the warranty is to check with a dealer and see what their opinion is. The vendor should also be able to tell you. As far as cold air intakes go, the stated horsepower increase is usually at high RPMs. Unless you're going to track the car, you probably won't notice that performance increase very often.
I agree with the Lloyds mats. Especially if you get the high-end versions. They are very plush. Check them out.

 

Is there a significant power increase with the addition of a cold air intake system?

 

Welcome to the forum.

In a word, no they don't. Check the vendors website for dyno data. Most of the ones I've checked out show about a 7-10 horsepower increase at the upper RPM band. You're not going to notice this on the street.

 

Thank you.
