    Default How much effect would a decent Cold Air Intake Have on a 4 Cyl Auto?

    I was thinking of spending around 200ish and getting a decent cold air intake for my 4 cyl.. is it worth it; how much HP out of it.. if much at all?

    Depends on what you're looking for. I'm guessing not many are posting because they don't know your end destination. Are you looking for something to compensate as much to feel like a 6 cylinder? If so, then don't waste your money and save for a conversion. There's a lot of stuff out there that claim big power gains. Nothing will get it like the straight six. Then again, there's a lot of people that invest in their straight six to try and get them to be a v8.

    A lot of people invest in their 4bangers. More power to them. I invest in a 25 year old CJ, so who the hell am I to judge

    If you just want a tiny bit more "power", I'd probably just gear it a little higher. Looks like your on aftermarket tires. How big are they?

    If you want rumble, you're SOL. haha. The I6 sounds okay with aftermarket exhaust, but that shit gets banged up easy on the trail (depending on type of wheeling). Again, this is all my opinion based solely on how I wheel.

    what transmission? auto or manual? upgrading tire size without regearing will kill your 4 cylinder. If I were you I'd regear and go from there.

    your factory gears carefully balance power and fuel economy for the factory size tires. when you get bigger tires, the balance is knocked off and you lose a lot of power per inch of tire size. this is especially felt with the 4banger. I don't know much about the gear ratio chart on 4 banger autos, but I'm guessing you should regear to 4.88's or 5.13's. This will help you get the power back a little bit. The gears are in your front and rear axles. Usually a pricey deal, but worth it in the end.
