These JE pistons for DAZA 2.5T were made to CTS spec of 9.3:1CR which is 0.7 lower than factory. This slightly lower compression allows you to run more boost and make power without sacrificing off-boost performance. Most software tuners prefer this compression ratio. \n \nThese JE pistons feature the latest in technology and performance. The innovation and research that JE puts into their products makes these the best pistons on the market. Made by JE Pistons in USA. \n \nIf you're looking to get the best engine internals for your high-power 2.5T build, then your search ends here. \n \nJE's revolutionary, patented Perfect Skirt coating makes piston slap, false knock, and cold-start wear a thing of the past. For the first time ever, 2618-alloy pistons can be installed with piston-to-wall clearances near that of an OEM piston!  \n \nThese pistons are compatible with both the factory APS cylinder walls AND aftermarket iron sleeves. \n \nFeatures: \n
