These cylinders are an average product trying to cash in on fancy marketing, they’ll do the job if you just want a mediocre replacement part shipped relatively on time but don’t expect them to actually improve performance.

These evolution-style aluminum cylinders are top notch, with their attractive natural finish, larger 3 1/2-inch bore for more power, quality manufacturing right here in the USA, and hassle-free installation with dowel pins – you can’t go wrong upgrading your Evolution engine with these cylinders that customers say are well worth the wait.
