Just finished doing the deckplate and ISR mods on my car. To go along with these i dropped in a Amsoil air filter, Amsoil motor oil, and amsoil super duty oil filter. I did the Oil and air filter last week and the mods yesterday. With just the oil and air filter i noticed a HUGE difference in accel and fuel economy, i cant wait to see what the other mods do for me. i also have sound files of before and after the mods were done for anyone that wants to do this but is worried about sound.
