Our Gen 3 Hemi heater hose plug are made to get rid of the heater hose tubes in a race only application. It removes a few pounds & reduces the number of leak sources for coolant.
They need to be welded in when the engine is still apart. They are tapped with 8mm x 1.25 metric thread for bolts for the brackets or if one ever needed to remove them. We also have shorter untapped plugs to be welded in for those who still have their engines apart.
Made in USA of 6061 aluminum, the set is with 2 plugs & 2 bolts, one for the timing cover & the other for the water pump on passenger car 5.7, 6.1, & 6.4 Gen 3 Hemi's. You will have to fabricate your own brackets though.
Choose between the taller set-in plugs with flange bolts or shorter weld in plugs.
