It is a great thought for many people and certainly a simple thing for them to do
3/5

The thought is appealing, and it is a fairly straightforward process for many to implement. I got it installed in a short amount of time. On the other hand, due to the angle of the heat shield, on the bottom of the filter was a little more than 1/2" clearance, and on the top was about A five-point plan. As a result, getting the supporting ring in place and tightening it was a painful experience. When I drove it for a short period of time after installation, the filter fell off because there isn't enough room around to make sure the filter is seated properly. Keep a screwdriver in your truck so you can use it when you need it. That's really sad that K & R didn't make it The installation was not a one- or two-piece system. The OEM supplies less parts than we do, as we have so many.

The installation process is simple
4/5

I found the installation to be easy. It will be difficult to remove the filter element for cleaning because it is so large. You have to place the filter in the air box before you secure the ductwork to the air box, so I knew something was amiss. Other than that, I'm a huge K&K fan The following products are available.

There is no noticeable difference
3/5

The box was missing an elbow and part of the intake had to be rigged in, which took longer than expected. I have not seen a higher power level or better mileage though it has only been a few hundred kilometers?.

No big deal
3/5

Despite an easy installation, the fixture does not fit well. It is difficult to remove the filter to clean it. I cannot tell if HP was added in the process. I will be looking for a replacement item.
Update Power gain is not the case, it takes a lot of time and effort to remove and clean, so don't.

Neither the gas mileage nor the performance have improved. One thing I like about this is that I can see if the air cleaner needs cleaning without having to remove the.

The price is OK, and the intake tube fits well on my 2015, but I wish KN made a complete tube rather than using three silicone adapters and eight
