deckplate mod and isr mod like 20 dollars and i think it works better
Eh, for me there is too much debate whether those mods work or not, Supra725 has a K&N and I liked it a lot. I just picked up a magnaflow 18" too and I think combined I'll get better performance and mpgs. Besides I can always sell the K&N. OFF TOPIC (I dont want this thread to turn into another deckplate debate)
So, does anyone know the answer to my question?
