IE Spec Mahle 1.8T 20V 92.8MM Stroker Piston Set

Upgrade To Mahle Pistons As A Great Solution For The Street And Track

We have teamed up with Mahle once again to design the ultimate 1.8T stroker piston set. As with all of the other Mahle pistons we offer, these pistons come to the table with industry-leading features, OEM fitment, and OEM-like wear characteristics. These pistons are recommended for any high-performance engine build, as they offer unparalleled strength and longevity.

Features

In order to offer a piston set with the strength to withstand high power numbers and the longevity to last for thousands of miles, we started with the heavy duty forging that is used for direct injected applications that see higher cylinder pressures than the 1.8T. We then designed them with the specs that we have tested to work the best for the 2.0L stroker setups, using an 83mm bore and 92.8mm stroke. We offer these pistons with 9.25:1 compression ratio, which we have found to work effectively for street applications as well as higher horsepower applications. To maximize power output, the clearances between the rings and piston have been brought in very tightly to reduce blow by. This is achieved by hard anodizing the top ring lands, which prevents micro welding which could be caused otherwise. To maintain OEM-like wear characteristics, these pistons are coated with Mahle’s Grafal skirt coating. This coating reduces friction on the skirts, keeping them quiet and from wearing over time- extending piston life. The grey appearance of these pistons is due to a phosphate coating. Providing a lubricant film in the pin bores and ring grooves, this coating is essential for initial startup and break-in of the engine to prevent micro-welding and galling. Features like these are what allow these pistons to last for thousands of miles, just like OEM units.
