    EJ25 Seal Tight Sleeves by Darton

    Subaru blocks are made out of aluminum and can sometimes react adversely to heat, slightly changing clearances with temperature changes. This consequently makes the engine less consistent and less reliable. Inserting a Ductile Iron Dry Sleeve into an aluminum Subaru block reduces the amount of warp, and remains a consistent size and shape through its operating heat range.

    Dry Sleeve means that the sleeve does not contain water/coolant passages bored through the sleeves. This solid design provides a more rigid structure to prevent warping and sleeve expansion.

    • Bore - 3.890
    • O.D. - 4.250
    • O.D. 2 - 4.200
    • Wall - 0.180
    • Length - 4.800

    • Flats - 2.223

    1.) All MAPerformance in-house fabricated parts include a Limited Lifetime Warranty for the Original Purchaser. This warranty only applies to the original purchaser and is non-transferrable.

MAPerformance will not be held responsible for additional costs due to the failure of a product (cost of sale, towing, labor, etc.). Warranty claims must be submitted to MAPerformance for review.

    3.) You must create a support ticket to acquire your return authorization number prior to returning the product.

    4.) Warranty claims will not be honored if the product was not purchased through an approved dealer.
