Now that I bought my exhaust, I might as well buy cold air intake, too. I have a '98 GS, and I was wondering...
About how much HP will I gain from AEM cold air intake? On the package for the exhaust, it said 10-20HP gain (haha, 20 my ass), so I have a reason not to trust "official" statements.
Also, I noticed they sold that bypass valve seperately. I live in socal, so it's probably not really necessary for my to buy it, especially at this time of year. But, I'm probably going to be moving to either Kansas or Illinois within the next few months, where the weather is pretty much the complete opposite. Would I need a bypass valve just to rest my mind when I move? What is the probability of hydrolocking my engine out there?
Lastly, what's the cheapest place to buy it? You're probably gonna say EBay, so I guess I just answered my own question. Thanks in advance for any help!
