Tempest engine mounted oil filter adapters eliminate the need for oil screens and provide increased filtering capabilities for longer engine life. Being engine mounted with no external lines, they reduce mess during oil changes and increase the time between oil changes.


Note: Tempest filters are included with adaptors. Price listed is for one adapter each.

Does not fit C182d. Would have to reroute everything on the firewall to non factory positions or move the motor mount... Neither of those are going to happen... If you do try it, you will get charged shipping to return the item and shipping from when they sent it to you. They refund to store credit as well, instead of your card...

This adapter is a good solution if you have an O-300 with an oil screen. If you have a Ford alternator, there may be a need to remove a small amount of material from the alternator case to fit the adapter properly. Mine arrived with the safety wire holes pre-drilled per the recent SB.

Be aware the TAF-L will not fit a J3 Cub without cowl modification. Tempest and Spruce need to list exactly what Cubs it does fit. Providing the customer with detailed information they have after purchase and paying international freight isnt a good look for Spruce.

Great upgrade for any O-200. Every 150/2 should have one of these.

I ordered the Oil Filter adaptor TAF-L for my Cessna 150L (1971) . The order arrived very well packed and arrived quickly. I have it installed now during Annual- Very Happy with the product- also received a copy of the STC and C of C (FAA 8130) .Aircraft Spruce is a great company to work with.

Wish the STC was printed darker...kinda cheap copy and hard to read. Otherwise great product.

Easy to install in an IO 360K, had to remove alternator for filter housing to clear but, expected that. To get to 65 ft lbs, a 2nd pair of hands holding the housing so, it wont spin, was required. Overall, its nice improvement over the originals.

Q: Are these FM engine mounted oil filter adapters FAA STC Approved?

Yes, these are STC'd.

Q: Is the STC paperwork included in the box with the FM engine mounted oil filter adapters or does the paperwork need purchased separately?

The STC paperwork is included in the box with these FM engine mounted oil filter adapters.

Q: Are these adapters made from a casting or billet aluminum?

These are made from a casting.

Q: Is everything I need to install the F&M mounted oil filter adapter included with the kit?

Yes, it will come with the filter, adapter, gasket and instructions.

Q: Do you need to be an IA and file a 337 or can an A&P install on of these F&M engine mounted oil filter adapters?

Per Vendor: An A&P, working under/for an FAA repair station with a designated inspector inspecting his work, can install, complete the 337, and sign off installation of an oil filter adapter if he has the knowledge of how to do so. If working just with his/her A&P license, he/she can complete the 337 as well as installing the adapter, but has to have an IA sign after it is completed.

Q: What other filters can be used with these adaptors or does the STC require the use of Tempest filters? Use part # 08-00631 for example.

The only filters that will fit and work properly with adapter # 08-00631 are the Tempest AA48108-2 or the Champion CH48108-1.

Q: The STC for the Tempest Engine Mounted Oil Filter Adapters is for the engine, not the airframe, right?

Yes, these are STC'd for the engine not the airframe.

Q: Does the adapter screw into the suction or pressure screen opening? Also, I don't see any thread on the adapter in the pictures but I presume that it is there?

Per Tempest: This would mount where the oil cooler would be. This doesn't screw into where the oil screw is.

Q: What oil filter # works with the 08-00634?

The Tempest AA48108-2 filter is used on this unit.

Q: Does the CO-300 have the ability to accommodate the temperature probe that currently installs in the back of the oil screen?

Yes, this has provisions for a temp probe.
