As someone with zero experience changing air filters, I was honestly surprised at how easy this was. The fit was perfect for my 2010 Honda Accord Sport, and both the cabin and engine air filters installed with no issues at all. It even came with clear, easy-to-follow instructions that made the whole process stress-free. Saved myself money from going to the dealership, and my car is running great. Definitely recommend for beginners wanting to do a simple DIY maintenance job.

Great value

The engine air filter fit perfect. The cabin air filter was a bit of a challenge fitting. seemed to be a bit larger but it went in and got the cap back on the box. For the price you cant beat it. Would buy again!
