Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements. They are CNC machined from extruded 6063 aluminum, media blasted, black anodized, and laser etched for a high quality surface finish. Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors are permitted. The fuel rail is equipped with features to accept the OEM fuel injector clips

This kit is compatible with all fuel types including popular alcohol mixtures such as E85. The OEM insulating spacers (Honda P/N: 16638-PNA-000) are reused and washers are included to thermally insulate the fuel rail from the aluminum intake manifold.

The fuel rail ports are tapped for 8AN ORB. Fittings ARE NOT included with the fuel rail and must be purchased separately.

Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.

This fuel rail is compatible with all OEM Honda K-series intake manifolds (RBC, RBB, RRC, PRB, etc). If using an aftermarket manifold (Skunk2, etc) check with the manufacturer about fuel rail compatibility. If the manifold fits the OEM fuel rail, then the Radium fuel rail will also fit.

    Great shoes!
    Size: 5 Big Kid, Color: Light Grass Green
    This is my second time purchasing these shoes! Not only are they stylish and well made, but they are comfortable! These have been used as running shoes, they have great support and suitable for long distances. The fit is true to size. Thank you!

    Shoe laces aren't great.
    Size: 3 Big Kid, Color: Black White
    I bought these RUNSIDE kids tennis shoes for everyday wear and school, and overall they’re lightweight, breathable, and comfortable for active use. My child liked how easy they were to put on, and they worked well for running and general play. The shoes themselves feel flexible and pretty comfortable for the price point. The upper material is breathable, which helps during sports or warmer weather, and they don’t feel heavy on the feet. However, the main issue is the original shoelaces. They constantly came untied no matter how they were tied, which became frustrating pretty quickly during the day. We ended up replacing them with better-quality laces, and that solved the problem. Pros: * Lightweight and comfortable for kids * Breathable material works well for active use * Easy for everyday wear and school * Good fit for the price Cons: * Original shoelaces do not stay tied well * Laces needed to be replaced for practical use Overall, these are solid budget-friendly kids’ sneakers that work well once the laces are swapped out. The shoe itself is comfortable and functional, but the included laces are definitely a weak point.

    Great shoes
    Size: 8 Toddler, Color: Camouflage Gray
    Bought these for my three-year-old son, they fit great and they are easy for him to slide on himself. The laces seem to come untied a lot, but otherwise we love them!

    Perfect for Active Kids
    Size: 4 Big Kid, Color: Black, Size: 4 Big Kid, Color: Black
    My son loves these shoes. He says they’re really comfortable and lightweight, and he can run and play in them easily. So far they’ve held up well. He can fit them. Non Velcro and slip resistant.

    Good, but not great! Insert kept falling out.
    Size: 3 Big Kid, Color: Black
    I bought these for my 8 year old and the insert was loose and had to be played with multiple times before I could get it to stay in place. I eventually had to place a double sided sticky pad to get the insert to stay.
