🚀 K&N Cold Air Intake Kit: Boost Horsepower & Performance for 1999-2004 NISSAN Frontier and Xterra. 57-6005 model: 50-State Legal Review

This had a HUGE impact on my 2001 Xterra's fuel economy and overall performance. It immediately breathed better and I can say it really lives up to the brand, purpose and function! Would buy it multiple times for any other car!

Very easy installation. Everything fitted perfectly and the instructions were clear with step-by-step photos. Yes, it's more than unknown brands, but clear instructions, everything fits without problems, and the calmness of customer service is worth it to me.

2001 Nissan Xterra. The intake manifold was defective at the factory and had to be replaced. The KN kit is well labeled and the parts are great. It's not cheap, but if you're going to be leaving your truck for a while, it's a worthwhile investment. The filter is great and the setup just feels very high quality.

Fantastic filter. Installed on my Nissan Xterra 2004 3.3 with 110,000km mileage. I noticed a slight increase in performance, the car's sound also improved slightly. Very easy to install, I had very few tools and did it in 90 minutes. The instructions are very clear, if you can assemble a table from Ikea you can do it.
