Porsche 911 997 (2005-2013) 997 GT2, GT3 & GT3RS (2006-2013) Engine Intake Sleeve Kit - PFR57-526K Supplied as an engine set of 6, our new PFR57-526K Engine Intake Sleeve Kit is made in our Dark Grey 80A polyurethane material for an OE aesthetic with increased durability and reliability over the equivalent rubber items which from what we have been told, are no longer available from Porsche! Each sleeve is designed and engineered to seal and link both sides of the intake system, with the supplied high-quality, stainless-steel hose clamps ensuring a tight fit and consistent engine vacuum, making them a must-have for any engine build. Please note, this kit fits 996 GT3 & 997 GT3 models only. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
