This is a great deal for anyone wanting/needing a piston upgrade from stock.

I ran a 95mm version of this piston in my engine - it required the cylinder to be bored.....this one Lancer is selling is 94mm and will fit into a stock cylinder.  When I removed the piston after 12,000 miles to change to a different piston - the piston and cylinder looked great and there was no visible wear.  This is a reliable and durable upgrade, and along with other engine improvements I got a consistent 62mpg, no oil consumption, quick starts and a GPS confirmed 101mph!  (Other upgrades included Stage 3 cam, ported head, Mikuni carb, better muffler).

This piston will make a noticeable power improvement over stock....and it is a great price.
