K&N High-Flow Original Lifetime Engine Air Filter: Increase Power: Premium, Washable: Compatible with 1997-2009 FORD/Mazda/Mercury: Explorer, Ranger, B2300, B2500, B3000, Mountaineer, 33-2106-1

I purchased the K&N Engine Air Filter (33-2106-1) for my vehicle on November 22, 2016, and it has proven to be an exceptional addition. Designed for a range of Ford, Mercury, and Mazda models from 1997-2011, including Ranger, Explorer, Mountaineer, and others, this air filter has significantly enhanced my vehicle's performance. The engineering behind this air filter is impressive. It's not just about filtering air; it's about boosting horsepower and acceleration while improving the overall engine performance. The state-of-the-art air filter media is a game changer for anyone looking to enhance their vehicle's capabilities. Durability is a key aspect of the K&N Air Filter. It is made with rugged, premium materials, ensuring it lasts a lifetime. This is not an exaggeration, as I've been using it for years now and it still performs like new. The 4-layer protection system, featuring premium cotton gauze treated with a specially-designed tacking agent, creates an intricate mesh that effectively blocks harmful contaminants. This level of protection is vital for maintaining a healthy engine. One of the most appealing features is the low maintenance requirement. It only needs cleaning every 75,000 miles under normal highway driving conditions, which is roughly once every five years. This convenience is a significant advantage over regular filters. The cost-effectiveness of the K&N Filter is undeniable. It's washable and reusable, saving a considerable amount compared to purchasing multiple disposable filters over the course of 200,000 miles. The no-hassle lifetime limited warranty adds to the value, providing peace of mind regarding its longevity and quality. Additionally, installation is a breeze. The filter comes pre-oiled and is ready to drop into the factory air box, making it one of the most straightforward and cost-effective vehicle upgrades for quick performance gains. As of today, the filter is still functioning flawlessly in my vehicle. It's a testament to the quality and durability that K&N promises. For anyone considering an air filter upgrade, I highly recommend the K&N Engine Air Filter for its performance enhancement, durability, and cost-effectiveness.

Increased power and fuel mileage

Is as describe does breathe well Fits truck perfect and truck run great and all I do is wash and spray rec oil back on. Put back in No buying new one

Really increase the air flow

Fits a 2004 ford explorer sports Trac. Works well. Easy install.

I have measured the fuel consumption of my truck very well. It is 24 mpg. With this filter, the consumption remains exactly the same. What is certain is that it feels more agile in acceleration, which I can also notice.

Outstanding product

product fit well

Was soll man großartig zu einem Luftfilter schreiben?! Er passt zu in mein Auto. Da gab es keinerlei Probleme. Würde ihn auf jeden Fall wieder kaufen!

Way better then the others

Very easy fitment (like all K&N's). Engine runs alot smoother with, more throttle response.

I have a K&N filter in everything I own, including my quads. I would put one in a minivan if I ever owned one, they make a noticeable improvement on throttle response, power and even fuel economy.

My ranger was incredibly dusty when I first got it. Cleaned out the engine bay then took out the dirty filter and put this one in. Acceleration seems more responsive and just runs smoother in general. This is definitely pricey for a filter but I think this product will pay for itself over time.
