SpeedFactory Racing K Series Sidewinder Turbo Manifold for Honda/Acura

SpeedFactory Racing K-Series Sidewinder Turbo Manifold

Unleash the full potential of your K-Series engine with the SpeedFactory Racing K-Series Sidewinder Turbo Manifold — a high-performance turbo manifold engineered for serious street and race applications. Designed to maximize exhaust flow and boost response, this manifold provides lightning-fast turbo spool-up and a wide, usable powerband that pulls hard from low RPMs to redline. Whether your goal is to dominate the drag strip or carve through corners on the road course, the SpeedFactory Sidewinder delivers the performance you need.

Each manifold is constructed from 1.5-inch Schedule 40 stainless steel tubing for exceptional strength and heat resistance. Every weld is TIG-welded and back-purged to ensure durability under extreme conditions, while the CNC-machined ½-inch 1018 steel flanges guarantee a perfect seal and long-lasting reliability. The manifold’s precision-engineered design allows for quick spool of small to medium-sized turbos, resulting in reduced lag and increased midrange torque, while maintaining massive top-end horsepower gains.

Built to fit a wide range of Honda and Acura platforms, this manifold is ideal for K-swapped 1988–2000 Honda Civic (EF, EG, EK), 1994–2001 Acura Integra (DC), as well as factory 2002–2011 Honda Civic Si (EP3, FA5), 2002–2006 Acura RSX, and 2004–2008 Acura TSX models.
