K&N Filters Reviews

My 5th purchase from K&N. This is the only brand I use for air filters. Easy to find the correct filter on their website and delivery was very quick. As always the filter itself was high quality and easy to fit.... Those are part of 3 K&N Filters reviews. The latest review from Trustpilot - I recently purchased a K&N cold air intake for my 2006 350z. The installation was easy and quick. Unlike many other after market parts, this cold air intake fit without any addition modifications. It was simply a bolt on and go fitment was perfect and it looks awesome.. There are 2 excellent reviews. 0 of customers rate great. But there are almost 1 of people rate bad.
