I measured the diameter of the intake tube on my current cold air intake. It measured 3.5”. Based on my measurements and the adapter description in the ad for this filter I made my purchase. I am very pleased with this filter. Measuring first should be able to solve most complaints about a poor fitting filter. If your intake tube is 3”, 3.5” or 4”, this filter should fit. And it seems I can feel an increase in power/performance. Aside from this, the filter is a really cool looking part. Too bad it’s hidden under the hood of my SUV. (see photo) P.S. Be sure to securely tighten the large hose clamp that secures the filter and adapter(s), if needed, to the intake tube. So far everything is working well. I will update this review in the future should I notice any issues but for now, I’m super pleased.

The intake pipe I connected this to is 3.5 inch so I used the 3.5 inch adapter. This didn't work out and whenever I popped my hood to check it the filter had fallen off. I ended up removing all the adapters and putting the biggest 4 inch fit that it had and put it around the intake tube rather than the tube going over the filter like it usually would. This has been working and I don't think it will fall off anytime soon. After fixing that issue the filter has been perfect and feels high quality especially for the lower price compared to K&N filters. I also want to mention that I'm using a rubber intake tube with this filter and that might have caused the fitting issue. If you have a solid metal tube I bet this would fit better.

These were a quick fit for an unconventional use-case, vehicle-wise. OEM Bentley filters are about $105 each, and the car requres two. These cones saved a ton of cash and, IMO, look pretty great. Measure correctly and you'll be very happy.
