Darton Dry Seal Tight sleeves for the EJ25 Subaru WRX and STi engines replace your factory cylinder liners with a stronger, more durable and longer lasting surface that can hold more power and may be bored further than stock.
A 'Dry Sleeve' means that the sleeve does not contain water or coolant passages bored through the top flange. This solid design provides a more rigid structure to prevent warping and sleeve expansion.
Darton cylinder head sleeves must be finished at the machine shop and honed to the exact specs of the pistons going into them.
Vehicle Fitment:
2006-2014 Subaru WRX EJ25
2004-2020 Subaru STi EJ25
Includes:
(4) Sleeves
