K&N# E-1690 Fit?

[donalloy1]

Decided to spend the extra dollars for K&N# E-1690 Air Filter for my M1009. Cleaned and inspected housing before installing. All seemed to be as it should. Top cover does not seem to go all the way down and mate with bottom half of filter housing. Do not want to over tighten and squash out filter! Is it normal for there to be a gap between upper and lower housing with these filters installed? Does not seem correct.

Did not see any posts referring to this situation.

Mine fit great, but I don't remember what PN I got.

My 1690 fit just like stock,seemed to help bottom end torque,not sure though because I also made other mods at same time.I would not smash a nearly $60 air-filter.

Would take picture of installation
cpf240 but I doubt you could see gap! It's about .050 +/- Calling K&N tomorrow

Called K&N today and they asked me for Mold #'s off Filter. Will see what happens? Compared existing Fram to K&N and they look very close! Wall thickness and diameter is a little off. Must be what is not allowing Filter Housings to mate. Do I need to put my Micrometer on them K&N? More to follow. Fram back on for now. Howls like Banshee without Filter Housing mated!

So much for easy way out! K&N ran my VIN and told me that they could not match it up. The story deepens!
Now they want me to measure all dimensions of existing Fram that fits. Then go to their Website and match up dimensions off specification(s) list of E-1690 and another element. They are working with me, BUT this is not near plug and play I thought it would be! Suppose I should be thankful that I am fighting with Air Filter. Could be much worse.
Hope this is all resolved soon. Will put Micrometer on both. Call them back with findings and report back outcome.

1985 K30 with a J code 6.2 diesel engine is what you need a filter for. I have two of my trucks with the K and N. They fit right in without issue. I don't have access to my part numbers right now though.

Your filter housing could be crushed down a bit. I have seen that already. I don't know how it happened but somehow it did.

I have 2 K&N filters in both of my '86 trucks and they fit without issues. Next time I am at the truck I'll get the info off the filter for you.
