I'm aiming to replace my 2010 Civic's air filter. While looking online to see what stores have it, I noticed that none of the stores bother to mention the size/dimensions of the air filter. The only link I found was on Canada Parts Online, which mentions a specific engine (not cabin) air filter as
7 in. L x 6.5 in. W x 1.38 in. HPanel style
It looks similar to mine in proportions.
Are air filters a standard size, within and across companies?
