Great product, ready to install. there was zero issue with the product. only issue was Subaru's design makes getting to the plug a little hard but that has nothing to do with the product. great plugs!

We are glad everything was good to go! And yeah, Subaru didn’t make plug swaps easy, but at least the performance is worth it! Thak you for your 5 Star Review!
