Hello everyone, I just purchased my third vehicle, an 03 LS V8. I have been searching the forums for performance mods for these, but most of what I find is for the pre-03 LS's. My LS has the NAV system on SST shifter (very fun especially since my other two vehicles are manual). Anyways, my car has 59,000 miles on it and I purchased a platium extended warranty from my local Ford dealership. My other two vehicles are a 69 Mustang and 93 Chevy Z71. I can work on them but not on the LS. But what I want are some power adders that won't void the warranty. The first one I was going to do was CAI. I saw a thread that asked if K&N's CAI for the thunderbird would work, but the person never got a straight answer, so I am asking again. The only reason why I thought K&N is because they claim their filters will not void a warranty. If there are any others besides K&N, I'm very interested. Also does anyone know if altering the exhaust with high flow mufflers void the warranty. Sorry for the long thread but I am very excited and proud of my LS, but at the same time want more power and keep it covered by warranty. Thanks to everyone who replies. I just wish I could find a Mustang forum as informative and nice as ya'll. I will try to post a pic soon and if anyone is in the Souteast Missouri region, please let me know. I'd love to swap ideas/see mods in person.
