Fuel Filters: Z31 vs Z32

It works so do it.

The Z31 one works as well…does one work better than the other or something?

Yeah, I really don't see the benefit. If you're looking for more flow or something, look into some kind of aftermarket filter.

I heard the z32 filter out flows the z31 one. It is definitely larger.... flow more? Well I didn't notice a difference.

Larger /= more flow. Like said, makes more sense to just do an aftermarket filter. If you're needing that much more flow, you're going to be running AN lines at that point anyway, so might as well get a filter with AN inlet and outlet.

perefect. Ill be swapping a z31 filter by wix in then. thanks!

I was also pushing mine to 400hp. Does anyone know what the limit is on the factory Z31 filter?

I was making about 400 to the wheels and was having no issues with fuel delivery using a factory filter.

I've experienced no flow difference between them with the stock fuel system. The z32 filter flow ceiling is higher. Pumps won't care but interesting to if it would reduce current draw in certain situations.

I think a lot of people here have made 400+ on stock filter. I would suggest once you go to -6 or -8 an to upgrade to an inline filter that flows better so you don't have to worry about it going forward.

I have one, no noticeable difference.
