KIT PRICES VARY DEPENDING ON HOW MUCH I BUY THE PARTS FOR. PRICES GO UP AND DOWN. PARTS BECOME HARDER TO FIND AT LOW PRICE SO I HAVE TO BUY THEM AT THE NEXT BEST PRICE I CAN FIND.

Ported 6.2L L86 87MM Throttle Body

Kit is Plug and Play! Only thing you have to do is swap over the rubber gaskets from your old manifold new ones are highly recommended (not included i kit), swap over the bolts, map sensor and purge solenoid. No tuning required to be able to run vehicle. Only thing you have to modify is the throttle body coupler. You will need a bigger one or stretch the one you have on your intake. I highly recommend K&N Cold Air Intake Part number 63-3082 as it comes with a larger coupler making this swap look like nothing happened under the hood.

You’ll see

-Better acceleration

-Less lag

-Increased throttle response

-More horsepower and torque all over the RPM Band gains of 18-20 guy depending on vehicle modifications.

I’ve sold hundreds of these kits with all happy customers!

NOTICE: on the intake manifold I do NOT Remove the internal pillars. I leave them so manifold retains its structural rigidity so no issues will happen down the road. Runners are ported 7” deep removing all imperfections from miss aligned runners and inlet is ported as well.
