Good quality K&N for spares

Great price for a k&n filter. I struggled to find a 2.75 input filter without being too high. This one worked well for mounting directly to my Garrett turbo.

Pros
  • Dope 🔥
Cons
  • Appearance

Amazing cheap filter price.

This filter is well made, small and compact as you can see in the photo below left. I like that the size I added is 2.5 inches.

Pros
  • Easy to install
Cons
  • Expensive

The K&N Quality You Expect

This filter is very easy to install. It comes with everything you need including adapter rings to adjust the intake pipe size. Looks good too! Only time will tell if this helps my MPG.

Pros
  • Absolutely Amazing!
Cons
  • I will write later

Adjustable filters

I really needed this! For some reason, there are no filters smaller than 3 inches in the auto zone. Very annoying, glad I found this filter. Perfect fit for my 2000 Civic Si. Air filter 2.75 k&n.

Pros
  • Ideal for outdoor activities
Cons
  • old

Has stacking adapter

This is a very small capsule filter - good if you don't have a lot of room to squeeze it in. I really like that as size really doesn't matter in terms of airflow. A major downside for me is that it has something of a "universal" filter neck. They give you a set of rubber stacking adapters to give you the right size. In the end I was only able to "approximate" my piping size and had to stretch it a bit. This is a problem solver. If you are replacing a regular size filter, purchase a…

Pros
  • Easy to use
Cons
  • Legacy

Great Cold Air Intake

We have a 1.8t engine that we put in our Vanagon and needed a custom air intake (the airbox was too big to fit in) so we have this air intake filter ordered and it is perfect for our needs. It wasn't dented or damaged and it didn't have any filament inside like some of the other reviews. It fits as it should and would be perfect for our forced induction application. Get one that doesn't have a second inverted cone if you're really worried about it coming loose. It seems overly reliable, and…

Pros
  • Hands Free Operation
Cons
  • Negative Gift

Worth every penny, good for filters

I drive a 2015 Mitsubishi Mirage and it's a 3 cylinder car. Other than that there are no replacement parts for it because A was a three cylinder and B wasn't in high demand for a car like rival Honda Fit OR anything. Of course, I didn't buy the case for its performance. But I didn't have enough stock on the car, it was inexplicably big, it hurt my eye and it didn't work well. So I made a custom cold air intake from the throttle body to the filter. I used this cold air intake filter and am glad…

Pros
  • Pleasant
Cons
  • Some little things
