Air filter differences

Mattt · February 21, 2005

Is there a real difference between the two AC Delco air filters? There are 2 different #s, but I cant see any difference. Are there 2 part #s at the Chevy/GMC dealer(Chevy/GMC part #) as well?

Why are there two different #s and what are the differences? Thanks in advance.

^ that link states the 1518 is a heavy duty variety of the 1519. Odd that they would have a lower number for the HD one. Anyhow, that's the only difference I found on Googley.

Ive ran into the same info out there. The thing is, you cant see any difference between the two. What makes the 1518 "Heavy Duty?" Anyone know?

I haven't confirmed this myself, but I had heard the the 1518 HD has more pleats, everything else is the same.

Can someone confirm this?

I called my local Chevy dealer today and asked the parts guy about the air filters. There are 2 part #s for the different filter, however, he said there is no difference whatsoever between the two of them. They even retail for exactly the same price.

I know, why ask why,,,,,,but why would GM eff around with part #s, and such like that? Oh yeah.....I guess this is the company that sells the SAME truck as a Chevy and a GMC. Guess this proves where their head is.

Can anyone else in the know refute what this parts guy said about the filters being exactly the same??

TIA

Was there a reply there that got deleted?

I think he was trying to reinforce his post that there are more pleats on the HD. Even though the parts guy says they're exactly the same, you won't really know until you go in there and check them both for yourself. Tell us what you find when you get back from the dealer...

Well, I did go take a look at the dealer. What DEWFPO is saying might be right. I didnt count the pleats, but looking from the side, its possible that the 1518 has more pleats. It does sort of look like the pleats are tighter packed on the 1518 vs. the 1519. Thanks for the pointer on where to look DEWFPO.
