Mitsubishi Evo X Pistons by Wiseco

Own a 2008-2015 Mitsubishi Lancer Evolution X 4B11T and plan on building a motor? Wiseco is proven to make some of the best pistons on the market!

Featuring valve pocket designs that allow maximum flow around valve, also allowing oversized valves and high lift cams to be utilized. Piston crown shapes designed to promote maximum intake charge efficiency thru scavenging mixture "cross flow" during intake and exhaust valve overlap. More fuel and air equals more horsepower!

Great Pistons

I use to use another manufacturer for my pistons but over the years Wiseco has won me over. The design and machining are top notch and they are the best value available. They come standard with skirt coatings for no additional charge. If you ever need replacement rings or if they are out of spec from the box, the will ship you replacements overnight. Most companies charge for over sized rings even if they are small out the box, Wiseco doesnt or at least they didnt for me the 3 times i needed over sized rings. The wrist pin circlips on all Wisecos are the beefiest around. They require a lot more force to install but are definitely worth it.
