I did use this item it didn't do anything to help me. I used it a sendero it has been through about 10 firings. I'd like $80 for it that includes shipping (US Only) if your in Candada I'd Like $85. I was trying to sell it on ebay and it's a part they don't allow so they cancelled my listing. Below is a link to the product.
