  • Q: 05 STI block   Diego 6 months ago

    Answer

    Are these a direct fit for my 05 STI block? The heads do not have to be built correct ?


    • 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  fcbarajas0362538 1 year ago

    Answer

    How much power and boost are this rated for? I'm looking to build a motor that can handle 600whp.


    • A: These pistons will handle well over 600 WHP.

  • Q: Manley Platinum Pistons 99.5  michaelkeleman10038 2 years ago

    Answer

    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?


    • 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.
