Fram Ultra synthetic 7317 with light test

[Suzuki-2000]

This Fram ultra synthetic came off of a Honda CRV with unknown mileage. No light leakage from bypass area was detected.

That's good news. Anyway you can show us the leaf spring?

Since this is a used filter, and there is oil all over the inside, it could be if there's a small air gap at the leaf spring that the oil is essentially sealing out the light. Before cutting it open, take an air nozzle and blow all around the area where the leaf spring mates to the end cap to remove all the oil at that seam. Then retest for light leakage.

What's the date code?

Nice work! Thanks.

I had a Titanium pass not long ago that was made in 2023. Leaf spring looked perfect on that one.

I enlarged the date code. 68th day 2024.

Leaf spring also appears flat. No bow flex.

Call the Fram technical line, there is something wrong with that one, the full time bypass feature wasn't working at all.

After more contact cleaner & compressed air

Looks like you got a good one. Leaf spring is one of the better ones I’ve seen in a while.

Thanks! That one looks excellent & reason no light bypassed.

It might be wire backed based on the wide pleats by the seam that are still straight. If so, that would be interesting since the date code is the 68th day of 2024.

How can any conclusions be drawn when only inspecting from two angles?

Looks like plastic mesh, not metal on my computer at work.

Looks like plastic mesh, not metal on my computer at work.

Zooming in with my iPhone looks like metal. But it’s hard to tell.
