This HPS Performance Throttle Body Cold Side Charge Pipe Kit is an ideal way to replace and upgrade the stock plastic piping and standard worm gear clamps that are prone to pop off under boost, leaving you powerless while on the road. The 2.5" aluminum mandrel-bent aluminum elbow is designed with bead rolled ends to keep the silicone hoses from slipping off during boost. These high temperature resistant silicone couplers are crafted with 4-plies of woven polyester to easily withstand high pressure conditions. The 100% stainless steel embossed hose clamps in this kit are engineered to create a tight seal in order to eliminate air leaks without damaging the silicone couplers. Using OEM data, this kit fits perfectly into the engine bay and seamlessly integrates with your stock throttle body and lower cold side charge pipe. HPS performance kits are made to bolt-on with simple hand tools and do not require any additional modifications.
