SKperformance Posted November 13, 2004 Share Posted November 13, 2004 You are ingesting more air to the almost same amount of fuel thus causing a lean situation. Quote Link to comment Share on other sites More sharing options...
bartkat Posted November 13, 2004 Share Posted November 13, 2004 I don't think there is a true CAI for the IS300. There are various intakes on the market. You gotta make sure the filter has a "heat shield" with it or turbulence from the cooling fans will caus stalling at idle and low speeds. Some intakes will give a CEL because the MAF gets a different reading. Sometimes you can cure that via a ECU reset. The best bang for the buck is a JoeZ intake tube with a TRD replacement filter. Get's you about 8 HP. Total cost about $175 and the TRD is a Toyota part. For the most power, the SRT intake with piggyback ECU is tops. But with that one, you have to make some solder connections into your stock ECU, and the inakes cost around $500. http://www.swiftracing.com/ PS. You should already be running premium fuel in your IS300. Quote Link to comment Share on other sites More sharing options...
