Good Morning, all.
Yesterday, I replaced the air filter on my 2003 1.8T for the first time.
I noticed that the original filter looked a bit strange. It was the usual pleated paper sort, but it also had a pad of what looked like spun fiber glued to the bottom.
The replacement filter does not have this.
My question is, what is the purpose of this "pad" ? is it some kind of pre-filter?
Is it a concern that the replacement filter does not have it?
Thanks!
