jpc170 Posted August 8, 2007 Share Posted August 8, 2007 Hello everyone. I just got a lexus IS250 and love it. The only thing i was looking to do was try to increase my gas mileage a little, and gain a few extra HP. After reading through many topics i am at wits end as I have read people say they love them and others that say that they don't do anything for the Lexus. I did look under the hood and did see there is almost a ram-air flow by the grill. I looked into the Injen SP cold air intake which claims to add about 10 HP. Could someone please enlighten me on what they have fact on. Thanks Quote Link to comment Share on other sites More sharing options...
EnginePassion Posted August 8, 2007 Share Posted August 8, 2007 Do you think the 10 hp worth the problems that result from this mod? I, myself do NOT think so. Quote Link to comment Share on other sites More sharing options...

bartkat Posted August 9, 2007 Share Posted August 9, 2007 Not worth it unless you place high value on intake noise. Quote Link to comment Share on other sites More sharing options...
Tango Posted August 9, 2007 Share Posted August 9, 2007 I just fitted a 'JoeZ' intake in place of the OEM rubber convoluted one and a Blitz drop in free flow filter in the OEM cold air box. More efficient flow without noticable gain in intake noise...worked for me Quote Link to comment Share on other sites More sharing options...

I had one on the IS300 and have the same setup as you on the 350. Quote Link to comment Share on other sites More sharing options...
