Can someone tell me what spoiler this is here.
And does anyone know how to wash your engine, without ****ing something up such as alternator? Thanks guys.

 

thats the accolage combat wing for the gtr widebody kit.

you can get your engine steamed professionally, or you can just spray it with a hose and wipe it after its cool. you won't **** anything up unless you spray water into the intake and start your car. i kno they make some engine cleaner sprays that are out there. check an autoparts store like autozone ot pepboys....??
