Are there any other options for the GS400 other than SRT and the K&N FIPK? I was thinking of having one made, but my concern is will it cause any check engine lights and can the MAF sensor adjust enough for the change in airflow? I remember the SRT intake had some "ECU mod" that was supposed to richen the car out a little since they said it would cause the car go lean due more airflow...I thought MAF equipped cars could adapt for that. Otherwise I was thinking of adding a SAFC as well and then tuning it, but if I dont NEED the SAFC then I would pass on getting it. Any advice or info is appreciated.

 

I think the only one worth getting would be the SRT since it taps into the ECU and its documented to gain some HP.. just my opinion..

Columbos FTW on your SC430...

 

Well I'm 99% sure any intake will increase power...and I remember people saying that whole SRT ECU mod was a joke anyways....I'm just curious if people with the FIPK or those that have made their own intake have had any issues with CEL or it running weird....I have access to a fabricator who will be making me a full-cat back exhaust system and the guy asked if he should make me an intake as well since it looked so easy on this car.

I had the SRT intake on my old GS400, but I just think it was way overpriced and if I can put an intake on for ALOT less then I'd like to as long as it doesn't cause issues.
