Injen IS Series Short Ram Intake Reviews


Reviewed By Ryan C (SPARKS, NV) Reviewed for a 1992 Lexus SC 400 —7/27/2017 8:02 PM

Intake looks very nice and it seems to have made my engine run better. My engine had a slow rough throaty idle from the exhaust but now with this intake the idle speed went up and it is less throaty. Power seems the same but it feels like it gets to a higher rpm quicker than with stock. The hose was to long which is better to cut it than find a new one. You need your own 1 inch or so hose clamp, kit says to use stock but it does not work the new parts. Kit is better than stock :)

Lexus Intake

Reviewed By Jon K (Atlanta, GA) Reviewed for a 1992 Lexus SC 400 —11/30/2010 7:44 AM

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

Reviewed By Kristian R (Portland, OR) Reviewed for a 1992 Lexus SC 400 —10/30/2010 11:57 AM

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.
