## Description

Sold in packs of 6.

Review: Great product, easy install, improved performance - After watching a few YouTube videos I felt confident enough to handle the task. Spark plugs came quick and I was able to get right to the install. After inspecting the plugs for the proper gap, every seemed ready to go. Overall, it took be about 1.5 hours for the install as I wanted to make sure everything was correctly done. Install was smooth without any issues. It's been a little after a week after install and I've had no issues thus far. My truck had about 80k miles before changing out spark plugs and I've noticed an improved difference. Runs and feels smoother, gas mileage might be too soon to notice, but I'm positive there will be some improvements as well. Overall, the product has been recommended by the majority and I stand with them.
Review: Perfect fit for my 2007 X3 w/N52 engine. - Perfect for my BMW, right from the get go. Just buy it.
