These Shorty headers are constructed from 304 brushed stainless steel and heavy duty flanges. Designed with 1-3/4" primary tubes, these headers are built to retain as much mid-range torque as possible while still allowing for good top-end horsepower gains. These headers are designed to clear the stock cooling tube / "oil cooler" line found on the USDM driver's side of the block on late model VQ37 engines without issue.

Each manifold has O2 bungs positioned so you can use your factory O2 sensors.

ADAPTATION:

*WORKS ON ALL MODELS EQUIPPED WITH VQ35HR OR VQ37VHR ENGINE.*
