Awesome filter, my engine told me it loves the fit and ease of installation. It also it very good value for money as they aren’t expensive and you are getting a high value for the money. My engine also told me it’s getting slightly better fuel efficiency as well.

Made well

I just put it in but fits nice, good quality and I expect it to work very good. I watch many YouTube channels with experienced mechanics. Many of them use six products.
