Just tell them you were running it in your RV, and it shrank.

Default Replacement?

Will they give you a new one even if you have cut a little notch in it to clear part of the carb?

Default So please help me

I received my FF kit.
Nowhere does the part# E-3450 appear on the filter, only on inventory list. It was sealed in a plastic bag, no box. No VANS or K+N number on the bag.
On one side it says A077A6-T, on the other side it says A077A6-B.
The measurements are as supplied in Brantel's post.
It is round and not oblong as shown in the plans. What keeps it in oblong shape inside the FAB. (I have not build the FAB yet, but could not find the answer to this in the description).
Printing on the filter also says "oil before using". Is it OK to use as implied in this thread? Is there a way that I can tell if it was indeed oiled? It has pink/purplish color to the element.
Thank you.
Johan

When you build the FAB there are tabs that hold the filter in place. These tabs will make the filter form an oval. The filters come pre-oiled now (the red color on the filter) so no need to add anything except during future maintenance.

My last filter bought in 7/2012 already looks exactly like that in the OP. It has shrunk about 1.5 to 2 inches in only 1.5 years. I can't imagine keeping the filter on for 4 to 5 years. It would probably look like a donut.

Instead of ordering the filter from Van's, i think i will order it from the local autoparts store for $10 or $15 more. Then in a year from now, i will try and swap for a new filter under warranty with the original sales receipt.

Just found out the local autoparts stores dont carry it in stock. There goes that idea. argh!

Because of this post I've kept an eye on my filter, here it is after 31 hours on the tach. I really can't believe it shrunk that much, you can see the sharpie marks of the original diameter on the FAB.



A phone call to K&N followed by an email with pics and a description of purchase date, time in use etc netted me a new filter in the mail.

I'm curious if it's the filter or the installation/Fab that is making it shrink.

Did you install FAB drain tube?

I am wondering if those like me that installed the aluminum piece on the inside, which causes a little more clamping force on filter are having this problem?

Also what are your normal cruise altitudes? This filter is marginally sized for a 360 cu in at 2700 rpm, let alone my 540. If you fly low/high MP/high RPM a lot, you might be creating a higher pressure differential. I rarely fly low and rarely at high power settings due to birds(live and man-made).

Mine is exactly the same size after 135 hrs 2.5 yrs.

Today I replaced air filter with new after almost 1,300 hours. It deteriorated a bit during three years in service. It was cleaned and recharged at every condition inspection.






It held the same shape.







But it chewed a hole in the bottom of FAB which was promptly fiberglassed.
