I have purchased filters in the past and always find this trouble free and fast. As we live in New Zealand, this is not always the case.

Wow! What a great product, I felt the difference as soon as I started driving. The filter was a major upgrade and I felt the smoother acceleration right away. I was impressed by the fittment as well, it slid right in. I work in the hospital as the admissions coordinator, so I talk to alot of people and trust me, I will recommend K&N air intake filters to all.
