    Rated 5 out of 5 by from Great Price!! Not much to really review. I needed thermactor plugs. The other guys sold them for 8 or 9 bucks for one. Jegs had four for that price. Now I have extras for the future. Thank you Jegs for your awesome prices!!!

    Rated 5 out of 5 by from Saved my kit car project This was a life saver, actually, kit car project saver as I would not have been able to install the alternator and bracket without the Thermactor. What a great product. Thanks.

    Rated 5 out of 5 by from Thermactor Plugs Got the parts within a few business days. Exactly what I wanted/needed. These plugs fill the holes where your EGR valve pipes connect to your heads, if you were to remove them. They also fill the holes on the front of the heads, where your (alternator/power steering/air conditioning compressor) bolts thread into the heads, to hold them onto the engine. Correct part for filling these holes, or allowing you to attach your accessories.

    Rated 5 out of 5 by from cant beat the price I bought two packs of these a few weeks ago. I only needed one, but since I do alot of engine work I bought an extra set. Reason was two sets from Jegs was still cheaper than one from the dealer. Thanks for keeping hot rodding affordable Jegs
