2004 vs 2005 boxster S

[jsceash]

The 05 Has a slight power improvement. New air box. Larger MAF. Early 2005 engines still have a single row removeable IMS the later season one do not. Secondary air pump moved to the scavenge pump drivers side head. Transmission final drive is slightly higher. there are many other changes. Lights, Bumpers, body panels, wheel sensors, exhaust, windows, roll bars, and so on.
