Help....have had my 04' IS for almost a year w/ no mods. Looking to do upgrades but not wanting to void certified factory warranty. I.E., best shocks/lowering springs to buy, good wheel/tire upgrades, any other info suggestions would be greatly appriciated. Just bought a FIPK K&N intake. I have NAVI and am interested in the TV/DVD upgrade but wondering if that would also void warranty? HELP PLEASE!!!!

 

most mods won't void the warranty unless they can prove the mod actually screwed something up...

but if you want to be ultra conservative about your mods, you could go w/ factory mods - ie., L-Tuned stuff (l-tuned springs (1" drop on stock shox) and sways, which are really relabeled eibachs, l-tuned exhaust, which was made by HKS), and l-tuned wheels (18x7.5), by Rays.
go to a dealer, have them order and install it for you as a factory mod
problem is that it maybe difficult to source the parts and it's gonna cost you a LOT to buy and install by the dealer.

good luck..!

 

Thanks for the advice Junior. Ill call up the dealer...
Think if I buy THOSE items aftermarket the dealer will install...I ASSume not just cuz dealers are picky like that but..Ive never asked so I dont really know.

 

ummmm...when it come to warranty and the dealership... I have had my share of trouble...I had a short throw in my 04 and I (bent some shift forks while doing some normal driving ) the dealership told me that because of the short throw that this was the reason for bent shift forks ....and it didn't help the fact that I had intake and header with full exhaust .....took some bargaining and patience but in the end I got a new tranny all under warranty but from my experience every dealership is different...but good luck with the modding
