Review on 1221-308 Thread Repair Kit - Enhance Your Thread Repair with Thread Kits by Darrin Parasson

Excellent quality, worked much better than over the counter versions from China. Used to repair the studs on my BMW 535M M30B35, something I happily avoided the price at the auto shop for, this is also not a very common version of the engine. Also saved me from having to pull my head off the block, which I had done before recently and didn't want to do it again before riding it! The new headers sound amazing and the cleats hold tight! do
