excellent quality and fit

You can see a performance gain

Fits well

I don't know what these other reviewer's are talking about when they say this filter is not true to size. The inlet is perfect 4" and fits my 4" intake pipe to my turbo just fine. Great fitment, product true to size and came pre oiled. Even included 2 stickers. 10/10 would buy again

K & N filters are top notch, durable, cleanable. Fit was exactly what you except.

My original filter was in there for years this was a great replacement

Excelente calidad

Works as it should

The size is correct. It wasn’t damaged but prior to shipping should be packaged better. The box it came in is not made for shipping and could have easily been damaged.

Does not fit at all

Says it’s a 4” ID when it’s a 3.4” ID, waited longer than told for it as well, really not happy
