The Skunk2 Billet Ultra-Race Series Intake Manifold for Honda K20C1 / K20C4 engines solves the problems you will encounter when trying to push high boost to make Big Power. All Ultra Manifolds feature tapered runners with trumpet profiled entries and plenums that have been designed and optimized using CFD. Compared to the OEM plastic manifold, the Skunk2 Ultra Manifold has a larger plenum and runners for higher horsepower engines and won't come apart like OEM when boost pressure is turned up.


The manifold is designed with provisions to easily add and mount secondary port fuel injectors for high horsepower engine and turbo combinations. The Skunk2 Ultra runners are CNC machined from solid 6061 billet, while the plenum is cast from aircraft grade A356 aluminum and finished-off with our Signature Skunk2 Ultra-Series nameplate. The modular design of the Skunk2 Ultra Manifolds allows the plenum volume to easily be increased using simple spacers, and the runners to be freely ported for additional flow and volume. The versatility of this manifold allows enthusiasts and engine builders to tune the manifold combination to best suit their specific needs.

Features:

  • Tapered AL6061 CNC Billet Intake Runners
  • Modular Design with Removable Cast 3.5L Plenum
  • 1L Spacer Included. 2L Spacer Available Separately

    what a difference !
    Note: there are no English instructions. I wanted this cleaning agent to disperse throughout the nooks and crannies of the engine, so about ten minutes before arriving at the mechanic's shop for my oil change appointment, I pulled the car over and poured this into the engine, then drove it the rest of the way there. The mechanic reported lots of sludge drained out with the oil. The engine seems to perform and sound better, as if it's not working as hard.

    Buen producto
    Buen producto, limpia perfectamente el motor interno y se libera la suciedad en el cambio de aceite. no use todo el contenido, creo que es bueno usarlo en 2 cambios de aceite para una mayor eficiencia.

    Great will use it over and over again
    I will use this in every car I own from now. Cleaned it real well did exactly what it said so and my truck runs a lot better definitely can tell the difference.. it was work the extra oil and work. The bottle I bought came with instructions in English, which made it easy for me. The quality of it is light brake cleaner, but meant for engines and it ran great very easy to use this pour in.

    Does its job.
    Always a go to before oil changes. Helps remove some extra sludge/deposits. DO NOT DRIVE OR REV THE VEHICLE WHEN USNG THE PRODUCT, only idle for 10-15 min. Ive seen reviews where people drove with it potentially ruining the engine.

    Calidad de limpieza al motor
    Excelente producto, lo llevo usándolo un buen tiempo, en cada cambio de aceite, limpia bien por dentro del motor. Es fácil usarlo, hecharlo donde se llena el aceite del motor, y enciende el motor espere 10 minutos, y apague el motor, y vuelve a esperar 25 o 30 minutos para que se enfríe el motor, ya cumplido lo 25 o 30 minutos sacar el aceite viejo del motor. Listo, producto muy recomendable. Excelente funcionamiento, chevy silverado 2004
