Oil Filters Are Unobtanium

[Learjetter]

Sometimes you can buy the six-pack when the individual filters are sold out. I bought a six-pack earlier this year.

Joel, the order I referenced above is for the six-pack.

SOLUTION #1: Challenger Lifetime Oil Filter - Never buy an oil filter again! $315 to fit the Skymaster

SOLUTION #2: Install automotive filters that fit perfectly (and do the same or better job of filtering) - this comes from Beechtalk.com, where they have the same issue with their IO550's:

The Donaldson P169071 and Lifeguard LF3487 have outstanding filtration properties and utilize top of the line synthetic media for finer filtration than conventional paper media and could be seen to have the same thread size and dimensional equivalent of the CH48109 filter. It is believed that Donaldson and Fleetguard/Lifeguard are made by the same manufacturer.

Donaldson is about $18 https://www.dieselequipmentinc.com/products/p169071

and Fleetguard may be found for even less https://puredieselpower.com/products...er-lf3487.html

The WIX functional equivalent to the LF3487 is PN: 51515 but may only use conventional paper media (do your research on that), as it is priced at about $6 each https://www.amazon.com/WIX-Filters-5.../?tag=btalk-20
A case of 12 here for $50 http://www.discountfleetsupply.com/wix51515mp.html

K&N makes one that looks like a Champion - it has the hex nut on top and has safety wire holes. Not sure which model, post if you find out. Maybe this one? https://www.summitracing.com/parts/knn-hp-2004

SOLUTION #3. Use a Tempest AA48109 (If you can find one). They are now LEGAL for the IO360 and TSIO360: See advisory Letter attached. This filter is taller, so it may not fit???

Discussed with my IA yesterday and he likewise mentioned the challenger filter option. He’s got a few filters left that he keeps on hand for “corporate” clients who are blowing through the hours but is thinking he’s going to have to have some customers convert over to the challenger system to keep them going. His order is moving further and further out too. Flight school owner there obviously intensely listening…they haven’t hit the brick wall yet but sees it coming…

As a note, the Challenger filters, both the CP48108C and CP48109C, are out of stock nationwide until Sep/Oct. I also have had a six-pack, X2, order in with Tempest and spoke with them this morning. They will not be shipping until Oct at the earliest. They are also going to stop taking retail orders.

The K&N HP-2004 high performance filter is a match for the Champion CH48108-1 and the Tempest AA48108-2.

See photos below. Its almost 100% exact, only minor differences.

Has the correct backflow and bypass valves, and has safety wire holes.

$15.99 at Autozone, but available at most auto supply houses.
