I had contemplated purchasing an Intake and Exhaust system for my BK, but when it comes down to I can't justify hundreds and hundreds of dollars in parts that will only make my car feel a little faster and not make a noticeable difference. Nor would I save thousands to turbo my 9 year old 206K miles wagon.
The car may not be a rocket, but she's got decent pull if you give it some gas and with a few cheap mods will handle very
nicely. Just go auto-x it instead
