Wiseco ZRP 1400HD Forged Pistons for VW 2.0L TFSI (EA113 and EA888) Bore - 82.5mm 9.0:1 / 9.2:1

ZRP, in collaboration with Wiseco, has created a new and exclusive series of pistons manufactured in the USA from 2618 alloy. These pistons share many advanced features with the Wiseco HD1400 series for extremely high-power setups.

They include upgraded pins with a 5.34mm wall thickness and Armor Plating to reduce the negative effects of intense heat in turbocharged and nitrous/methanol setups. Each ZRP piston for this application features ArmorGlide anti-friction skirt coating to minimize wear during break-in and reduce cylinder wall friction. Our pistons are manufactured using proprietary forgings, providing a lightweight piston with superior strength and optimal design. Additionally, the valve pockets are larger and deeper than those of OEM pistons to accommodate high-lift camshafts. The pistons also feature offset pins and anti-detonation and gas pressure grooves to extend ring life.

What is Armor Plating?

Armor Plating gives them a bronze hue on the top and in the piston pin bore. This abrasion-resistant coating increases the hardness of the aluminum, improves the durability of the ring grooves, prevents micro-welding of the piston rings, reduces carbon buildup, and combats detonation corrosion. Furthermore, Armor Plating reduces the piston crown temperature by an average of 20 °C.

What is ArmorGlide anti-friction skirt coating?

ArmorGlide skirt coating is made with molybdenum solid film lubricant and is permanently bonded to the pistons. One of its main features is scuff resistance and friction reduction, ensuring quiet operation. Of course, piston rock, noise, and increased power are reduced.
