Bigger filter

dan323 · Mar 25, 2015

I just got a 2014 impala LTZ. I did a oil change yesterday to synthetic. I picked up a Napa Gold filter for the change and when I removed the ac delco filter, the Napa Gold was about 1.5 inches longer. I called and double checked at Napa and it's the right filter. So today I stopped at Advanced auto and checked the M1 and Pure one filters. They are the same size as
The ac delco filter. Other the a extra splash of oil there is no difference. So the question is.... There wouldn't be any performance issues to be concerned about, would there ? The car ran fine last night to work and I just don't want to risk engine troubles down the road.

No problem with warranty or mechanical if it is what Napa recommends for your car.

A lot of folks prefer the larger filter. It has the opportunity (but not a guarantee) to have more filter media available.

Napa Gold is a "house branded" WIX filter, one of the better filters available.

Wix probably uses the larger filter so they don't have to manufacture a new one. Nothing wrong with that. The bypass is internal I believe and the only thing you have to match up is gasket diameter and thread size.

Depends on the filter manufacturer's catalog. There's a tall and short filter that fits your engine. Short filter = about 6qts capacity, taller = about 6.3 qts.

You won't have any issues with either. Personally I like the taller one.

It's all good, in fact many ppl around here buy an oversized filter on purpose.

I might be doing it b/c the one for my car is always out of stock

Hmm. Could be be longer because the base end bypass takes up more room?

Cut the AC Delco open, take a pic with a ruler next to it for comparison then cut the WIX open after use. The media might actually be nearly identical in size.

Is there an oversize filter that fits new GM v8s?

Yes, but they might void your warranty.

Thanks Mom;

If the SAE 40 doesn't do it
the filter will.

Hey, some don't know that. So I say it. But I still use larger oil filters on my cars, bikes and motorhome.

If you want a larger oil filter for a late model GM engine, I would make a oil filter adapter like this(just make the inside threads match the stock threads, and pick the outside threads that give you the best filter for your car)

I made one for my supercharged 3800 V6 and had about 8 filters to choose from. I'm going to make one for my motorhome(Ford V10) so I can run a 2 Qt. oil filter instead of the FL820 filter.
