Big bore intake with 4.3L Throttlebody.


Do you have a healthy 2.8L, a 3.1L or 3.4L swapped into your Chevy S-10, Isuzu Trooper or Rodeo? This intake will save you time, money and frustration by providing a bolt in system that will allow your engine to breathe better. Forget trying to rig up your intake in your drill press or hunting the junkyards for a throttle body that has all the vacuum lines you need and the right throttle cable arm or TPS sensor. This system will provide you with an intake manifold with 1 11/16" throttle bores that is de greased and soda blasted. You will also get a 4.3L throttle body that has been modified with the correct throttle cable arm, the bolt holes for the throttle cable bracket, all 4 vacuum ports and the idle set screw un capped. The TPS sensor will be the new 89 and later style with a pig tail connector included for easy splicing into your pre 89 "S" truck or any Isuzu truck. Shipping is INCLUDED to anywhere in the continental US or Canada.
