Good fit, well made
These O-rings fit dimensionally the power steering pump on the 2006 CR-V. I only checked on the replacement pump, did not install yet on the car. These look and feel just like the originals, good quality material and well made, but only mileage can tell if they are as good. For now, all looks good.

as described
The size of these two o rings matches the description. Did not use in a vehicle so cannot speak on the fit of that, but size was accurate and they worked for my use.

Perfect Fit for Civic
Installed this engine cabin air filter on my daughter’s Civic and it fit perfectly. Installation was quick and easy, and the quality feels just like OEM. Great value compared to dealership prices.

Perfect Fit
The product arrived today and I installed it right away, no issues. The fit was perfect for my 2022 Civic Sport and the quality matches that of Honda OEM.
