I just recently purchased a 98 GS400, and I am debating on putting in a cold air intake. I was looking at the SRT High flow intake, it also comes with an ECU Chip I believe. What I wanted to get was the K&N because it is 300 dollars less. I was also reading in the ES forums and they were saying that the ES comes stock with a cold air intake, is this true for the GS and if so, what difference other then noise will I notice after putting in this new upgrade?
Can anyone tell me what kind of performance difference I will get vs stock.
1. Power curve
2. responsiveness
Also, will my engine check light come on if I install the K&N without the replacement chip?
