I went to Checker yesterday to pick one up. I'm glancing around at all the ones they have while I thumb through the book for what I need and notice most are about $3 and very small. I'm thinking, "cool, this will be even cheaper than I thought".
I get the part number, find what I need and it's as big as a friggin' oil filter! - LOL
On top of that it was $10, which is about what I expected originally; but I couldn't help but chuckle at the size of the darn thing.
