Air filter original part number

[Alpiner]

We have an after market air filter on our 2000 Alpine coach, and we can't cross reference the filter. Could some one help with the original part number ?

Thanks

Try AF22548 make sure that the seal on the filter contacts the end of the canister.

AF25548 is the correct Cummins number. Mine just came in after backordered for about 3 weeks. About $73.00 at Cal pac Cummins in Irvine ca.

Available from Ryderfleetproducts for $69.14.

Thanks for the reply. Just curious, Do all Alpines use the same air filter?

Thanks.

Nope--Alpines with the 350 hp engine take the 25548 while the 400 hp engines take a 25549 filter--think its engine size and not within year. Anyway, these filters are not inter-changeable. The 25548 filter has a slightly smaller opening--if you attempt to use a 350 filter in a 400 engine canister, the 350 filter will leave an air gap at the rear of the canister and you will "dust" your engine.

Just picked up a 25548 at Cummins NW in Chehalis WA, price was $59.59 with tax and power club discount. It did take a couple of weeks to get it.

Thanks to all for your help.
I have ordered one from Filter Barn for $51.00 including shipping.

I did notice that Jim Bragg's post mentioned 22548 as the number to use?

Thanks again

[Old Scout]

Again, think 25548 is the number for yr 2000. Just make sure the filter opening fits completely over the alignment cone in the back of the canister and the rubber gasket on the end of the filter is pressed firmly against the back of the canister wall--use measuring tape as you cant see it from the front.

I have a 2001 W/ 350 ISC, the 25548 dimensions don't match mine, no manuf. or part no. on filter or housing. Any ides?

[Old Scout]

Only know of the two sizes--dif is the size of the opening for alignment cone/clean air. What dimensions "dont match?"

[JerryF]

My measurements I.D 7.00, O.D 10.5- 11.5, the 25548 is I.D 6.05, O.D 9.85- 7.94. However the 25549 matches my dim. So thank you for leading in the right direction.

[Old Scout]

Dont think overall dimensions of the filter are as important AS LONG AS the filter fits inside the confines of the canister. What is of critical importances is that the opening at the end of the filter fits over the alignment cone at the back of the canister and creates/allows a good seal between the filter and the canister wall. If you try to use a 400 filter on a 350--it will probably work ok [trust but verify]--you may already have a 400 filter in yr 350 and dont realize it. Howerver, you cannot use the smaller opening 350 filter on a 400--a gap will occur and you will dust yr engine.

My 2001 8.3 ISC 350 hp, takes the (Fleetguard) AF 25549 so they changed to the new air filter so time in early 2001.
