The Skunk2 Ultra-Race Series Billet Intake Manifold, for Honda K series engines is the ultimate manifold for high-horsepower street and race engines. Unlike the standard Ultra Manifold, the Billet Ultra was designed for 8-injectors mounted top-side with a single fuel rail.

All Ultra Manifolds feature tapered runners with trumpet profiled entries and plenums that have been designed and optimized using CFD and on the dyno. The short tapered high-volume runners combined with a large plenum favors maximum top end power over lower end power and response. Skunk2 Ultra Manifolds also incorporate a modular plenum design where plenum volume can easily be increased using simple spacers, and runners that can easily ported for additional flow and volume.

After rigorous in-house and third-party benchmark dyno testing, Skunk2 has yet to test an intake manifold that can match the performance of the Skunk2 Ultra Race Manifold. The versatility of this manifold allows enthusiasts and engine builders to tune the manifold combination to best suit their needs.

The combination of the billet coolness-factor with limited production makes the Skunk2 Billet Ultra Race Manifold special offering.

*Does not fit K20C variants

The Skunk2 K-Series Ultra Street manifold is designed with an early style (PRB) intake manifold flange. Engines with the later style (RBC) flange will require the use of an aftermarket water bypass adapter.

    Works if you need help. Not a miracle in a bottle.
    Size: 1 Count (Pack of 1)
    It has worked every time I've used this product. Won't fix a damage catalytic converter but will help you pass the test if your car almost passed.

    Worked like a charm.
    Size: 1 Count (Pack of 1)
    Used it as directed. Down to an eighth of a tank. Poured it in and added enough gas to get back to one half a tank. Wanted to get it mixed in really well. Immediately jumped on the interstate and ran 75 MPH for 40 miles. Stopped and filled the tank and when I restarted the engine, the light was off. Coincidence? Not a chance. Light had been on continuously for weeks. AutoZone said I needed a catalytic converter. Nope. One thing I found out the hard way. If your gas filler has a flap at the top, make sure it is easy to push aside. Mine had a little release button near the top that the filler hose would depress before the flap would release. Dumped the first bottle right on the ground. Twelve bucks wasted. No one to blame but me, I guess. Still a bargain, even at twice the price.

    Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
    I read the specs on this product and it was guaranteed to cleanse as well as turn engine light off in vehicle. I received it March 14.2026 and used it on March 15.2026 I took a picture on Sunday before I entered it into the gas tank engine light was on at that time. Today is March 17.2026 and engine light is still on. The truck was driven for one hour on the 15th 45 minutes on the 16th and 50 minutes on 17 March. Still the engine light is on. Got home parked the vehicle took a picture again to show engine light is still on product guaranteed it was shut it off, but unfortunately product does not work.
