Replacing Engine Air Filter Question

[cyclonedave25]

I always replace the air filters myself and am replacing a friends. He got a Wix engine filter and it has a weird white padding/filter glued to the main filter. Something I’ve never seen before. Do I take that off or leave it on?

The one he got looks like this:

Tried both already. Couldn’t find an answer.

Leave it on. It's for increased filtration in dusty/dirty environments. Will do a better job at picking up the fine particulates.

Thanks, I’ve just never seen one on an engine filter before.

Yikes. If they don’t know, then you are first in the world and entering uncharted territory.

Godspeed.

I'd say as long as it still fits in the airbox leave it on. You'll figure out pretty fast if it's too restrictive.

That was my thought. Does the engine really need that extra filtration in the mid-west? Might do them a favor and have them change it out for a normal one and improve their performance.

It depends. I live on a gravel road so I like the prefilter.

Not a bad point. My thought was if this guy is in Chicago with the OP I doubt it is necessary right?
