Gen 2 - B58 Intake Manifold by CSF Radiators

The Gen 2 B58 cools its charge air inside the intake manifold, and the factory unit heat-soaks under hard use. CSF's replacement brings intake temps down further and recovers faster between pulls. That keeps the engine making consistent power and helps it stay out of limp mode.

What you get

• About 30°F lower intake air temps than the OEM manifold, per CSF.
• Faster IAT recovery after hard runs.
• Less pressure drop than the OEM core, which eases the load on the turbo at higher boost targets.
• Measured gains. On a roughly 400 whp car with bolt-ons, CSF saw about 26 whp and 11 lb-ft more than with the OEM manifold, and the gap grows as power goes up.
