I just put on the AEM cold air intake, and put the Toyo OC's 265/70/17s on my '03SC & it was/is WELL WORTH THE DIMES.

Before, it seemed my engine was 'searching' & if I had to hit the gas (automatic) to get me up a hill or pass, the gearing was such it wouldn't come out of gear for a while or topped the hill (which can be a while here in KY).

Now, there's plenty of power in the 2-3k RPM range vs. before.

Oh and incase other SC owners are wondering, the whine of the SC and new intake is priceless.
