Excellent product, came well packed and no damage, install was simple. Compleated the install in about 30 minutes including tool clean-up. A couple of notes, hose clamp on filter was a little small ended up switching to larger clamp I had on hand. Instructions direct you to install as staight as possible but when you do that the vacuum hose included in kit was about 1" short, it still worked but had to losen clamps and work things around. Also needed to use new hose clamps for vacuum hose, production ones were a little loose. Car seemed to have better mid-range power. Not sure of any increase in gas milage, have not had it on long enough to tell.
My Cold Air Intake
I wanted to replace my factory intake system. First generation Lexus, doesn't allow a lot of easy aftermarket modifications. I took the Injen system to my mechanic and he installed it in less than 20mins. I don't notice a ton of hp gain, but I'm satisfied with the overall results. Acceleration is smooth with an added turbo sound effect that's kinda cool.
