Fits intakes with 40mm stud spacing ONLY!


If your intake studs are the same distance apart as your exhaust studs, this WILL fit.

If your intake studs are narrower than your exhaust studs, you’ll need a 32mm intake. See my other listings for that.


Carbon fiber Reeds make the difference! They are lighter than metal, and stiffer than fiber. They will give you crisp throttle response, last longer, maintain their rigidity, and unlike metal reeds, they won’t tear your engine apart if they fail.

Type B Piston – high wrist pin – FITS ONLY ZEDA-80 and GT5 type engines. **if you are unsure if this will fit your engine please contact me first.

Intake Manifold is 19mm diameter. This is a perfect fit for stock carbs and SHA’s as well.


Includes everything pictured:

• 40mm Carbon Fiber Reed Valve.

• Type B Dual-Window Piston

• Piston Rings

• Needle Bearing

• Wrist Pin

• Cir Clips


6mm mounting bolts and intake gasket not included.
