All hardware including constant tension t-bolt clamps is supplied for an easy installation.

In recent testing, part number 46-20049 out-flowed the factory Intercooler tube by 67% and gave a stunning 16 max horsepower and 49 max foot pounds of torque increase at 1800 RPM which significantly lowered exhaust gas temperatures and increased MPG’s.

Part Number 46-20049 has an MSRP of $248.75 and is available in stores now.
