1.Hi, whats the best cold air intake to install on the car which will give the most horsepower, and how much horsepower will it add? Also how much is it and where to get it? Last, will it effect my warranty on the car?

2. I saw a picture of a tl and it had a bunch of white led's in the headlight housing under the hid projector light. Kind of like how the audi headlights look. What is it called and where can i get that as well?

Thanks in advance for your assistance!

 

1. think most people will prolly say AEM v2, i would say it affects your warranty on your stock intake, but if you take that out.... its not gonna void the warranty on other parts of your car, youll be good

2. yes that is AUDI LED style strips, you need to buy a strip open up your headlights and put them in and wire
