TRS Backflow Preventer (BFP) – Remote Oil Filter & Oil Accessory Adapter

Patent No. 11,555,425

Oil starvation & oil temperature increases are a problem that most Porsche enthusiasts who use their later model (1997-2008) water cooled Porsche model for sport & hard driving may come across, whether it be through the twists & turns of a scenic mountain view or around historic racing tracks such as Sebring or Spa. Our patented Backflow Preventer (BFP) restores the spirit of sport driving providing a better oil lubrication & cooling setup for the M96/M97 Porsche engine, improving engine reliability and providing you, the Porsche enthusiast, peace of mind while you wind through the gears.

Our Remote Oil Filter Adapter Backflow Preventer (BFP) goes directly in place of the original factory oil filter canister allowing for ease of installation of lubrication & pressure accessories such as oil pressure compensator(s), external oil cooler(s) and a larger, metal oil filter element. Our (BFP) also eliminates restrictive filter size spin on oil filter adapters and sandwich plate options by combining the two into one component & integrating a backflow check valve. Two key benefits here is our BFP will provide a greater ground clearance allowing for a much larger remote mounted filter to be placed, which will provide a better oil filtration and flow for the engine assembly, as well as the ability to connect & install multiple oil lubrication & cooling accessories.

Some spin-on oil filter kits currently on the market go in place of the original filter canister area, eliminating the possibility of having multiple oil system accessories, forcing you to use either an oil cooler delete plate with external oil cooler, a spin on “sandwich adapter” in conjunction with the spin on filter adapter to connect an accessory OR nothing at all with simply a smaller filter. This will also create ground clearance issues having multiple components sandwiched together with the inclusion of the oil filter, especially on lowered vehicles. The only way to prevent a ground clearance issue on that style setup is to use the smallest filter possible. If a spin on filter adapter & sandwich plate are used without the inclusion of a spin on oil filter, ground clearance will not be the issue at hand; the connection of multiple oil lubrication accessories becomes limited and the greater number of items to purchase increases to have the same oil kit solutions found with our (BFP) stage kits. A remote oil filter adapter and filter will still need to be placed. Save time and money with our (BFP).

A sandwich adapter combo with the spin-on oil filter will also require the use of an external oil check valve which has a maintenance life and will need to be replaced overtime. The (BFP)’s integrated check valve has a lifetime service life eliminating the need to replace a check valve.

Smaller filters are a lot more restrictive on their filtration and will have decreased service intervals. Compared to the original factory oil filter element and other smaller spin-on oil filters, the larger oil filters found on our (BFP) kits diminishes dry starts under cold cranking conditions due to low restriction design & internal anti-drain back valve assuring immediate oil flow. The larger filter also has a greater burst pressure of up to 500psi designed to take pressure spikes in race engines that have higher oil pressure.
