It's been a few years now that I've purchased and installed a cold air intake for my 2005 Scion xB. Now this car is obviously not meant for major performance tuning, but this is the type of car you don't leave stock if you want it to be fun and worth looking at. This intake fits perfectly and clears up a good amount of space in the engine bay. Combined with the right header and cleaner bent exhaust, even my dinky xB has a much richer and smoother sound than any aftermarket exhaust setups I've worked on (the intake alone instantly makes a difference in sound). I'm a fan of cold-air intakes, and also a huge fan of AEM. They have become my go-to company for CARB legal cold air intakes here in California.
