1. Most Wiseco pistons have offset pins. Pins must be offset same as o.e. for quitest operation - pin offset will be opposite of direction of engine rotation.
2. This piston is a flat top w/out valve pockets, to be used if verifying piston to valve and piston to head clearance.
5. There are different versions of this engine for Audi - do visual inspection of dish/valvepocket area to verify compatibility.
- Some pistons are listed with a range of compression ratio's. The low number is determined with an un-cut deck and the higher number is determined with .030 piston to cylinder head clearance.
- Always check piston to valve clearance - If using VTEC or like mechanisms-check with longer duration higher lift lobe.
- Always run at least .030 piston to head clearance including gasket thickness.
- If piston appears to be different than expected, please do not hesitate to call Wiseco at 800-321-1364 to verify compatibility
