I had the same problem, I talked to Amsiol and they told me to just stuff it in. The extra is to allow for shinkage over timeOriginally posted by Doug:
I just received my amsoil air filter for my Toyota 22re. It doesn't fit. It is off by about 1 cm all the way around. Has anyone else had this problem with amsoil air filters? If so, how did you fix it?
