No improvement over low rpms, you can't really feel it until flooring it on 2nd and 3rd gear, the car go so much quicker....its basiclly silent unlike the Area51 which I like, I don't like loud Intakes really...Had one and enjoyed it but time to changed...want the Is300 smoothness back..If I want a racey and nice juicey engine I will just go for a 3S-GE... , But yeah while doing 80kmh and floor it to 140kmh its so quick...and when I start off at lights on 2nd and 3rd its real quick...I m using the PLP Filter and its actually really good quality, no Idea why those US guys say its *BLEEP*...Its got 2 layers of foam and a layer of Honeycomb mesh for air cooling down, a nivce simple Intake for a reasonable price...enjoying it, Next performance mods is probly Lsportline Muffler then Toyomoto Headers...
