Key Features:

  • Each size includes precision tap, installation tool, and correctly sized drill bit
  • Total of 48 thread inserts included across all sizes

The Heli-Coil system creates permanent, wear-resistant threads that distribute stress more evenly than the original tapped hole.

Great price and good company to buy from!

so far, so great!

I ordered CV axles from Autoplicity and had them in less than a week! Definitely the best prices for quality product on this item. Will be a return customer for sure!

I was apprehensiveness at first to make a major purchase with Autoplicity due to their extremely low price and lack of reviews. I decided to take the chance and I am very glad I did. I made my order on a Monday morning at 0900 eastern time and my product arrived on Wednesday at 3pm. The item was exactly as described and the most astonishing part is that my purchase was released from the factory less than 45 days ago. I was expecting a model that had been sitting on a shelf for the last year and needed to be updated. That was not the case. I will definitely order from Autoplicity again in the future.

Very good price. Super quick delivery. Will def. buy from them again. Highley recomend them

Sweetest price on this K&N Filter anywhere! Shipped within 24hrs too. I'm coming back to shop for my car next.
