Features & Product Details

These pistons have been machined from lightweight 2618 construction, and they are ideal for those of you looking for a strong piston to sustain a high-horsepower or a high-boost build.

    QUESTIONS & ANSWERS

    • Q: 05 STI block   Diego 5 years ago

      Are these a direct fit for my 05 STI block? The heads do not have to be built correct ?
      • 0 of 0 people found the following answer helpful

        A:  The heads do not have to be built for these and they are a direct drop in but typically you will want to get the block honed to these pistons.

    • Q: Piston  fcbarajas03625385 years ago

      How much power and boost are this rated for? I'm looking to build a motor that can handle 600whp.
    • Q: Manley Platinum Pistons 99.5  michaelkeleman100386 years ago

      Have a 2013 WRX with a new shortblock coming from Subaru. Thinking of dropping these in. Are you able to get these graded by A or B bores? Will I need to fit the rings? Could I use the stock rings?
      • 0 of 0 people found the following answer helpful

        A:  These are not graded by A or B bores since Manley only uses those grades on individual pistons and not the complete sets. You won't need to use stock rings since these come with their own ring set.
