The MAHLE PowerPak is a complete, race proven piston assembly kit composed of hand deburred, forged, performance coated pistons, high quality steel pins, round wire locks and low drag performance rings. Performance coatings include a phosphate dry lubricant that is used to protect against ring micro-welding and pin galling
during initial startup and break in. For added performance, MAHLE applies its proprietary Grafal antifriction coating to each piston skirt.

The MAHLE PowerPak is now available for most popular performance applications in a variety of bore, stroke and crown combinations. The PowerPak is bringing a new level of performance, ease of use and
value to Sportsman level racing and performance enthusiasts.

Ordered a couple of items. The first was a air intake kit. I had put in all my info for my truck and chose one from the list to order. Won't fit. Called to tell them and they asked if I had called manufacturer...ummm no. Said I needed to contact them to verify wrong part. They were closed, so went to website. The part they sent me was a universal fit- for cars, not trucks, but did find right model- $90 more. Called back autoplicity and was told I need to go through email to get an RA# to return wrong part- site says I can call. Been on hold for over 20 mins and still waiting. Hope the Nerf bars I ordered fit! Update- they called me back, got my RA#. Very pleased with how Nick handled things- it was what I expected the first time. He verified the NERF bars will fit and will be changing the website so the universal intake does not show on list for vehicles with larger air outlets. Changing my rating to show my satisfaction with how it was eventually handled.
