Billet Oil Filters

TTA filter, notice the wider base.

Please email me on availability of this product BEFORE ordering, filters are available but I will need to see if they are in stock at the manufacturer who is close by to me.

ALL FILTERS ARE NOW MADE IN BLACK ONLY!

Heat sink ribs add to filter's functionality and aggressive aesthetic. The filters end cap is easily removed with four bolts for filter element inspection and replacement. The 25-565 longer 6.25" filter has a 4-5/8" tall synthetic fiber filter element which flows 45 GPM of hot engine oil with no loss of pressure and filters down to 8 microns comes preinstalled.

The 25-545 short 4.25" tall billet spin-on filter has a 2-5/8" tall synthetic fiber filter element which flows 15 GPM of hot engine oil with no loss of pressure and filters down to 8 microns comes preinstalled.

We also have a filter that will fit the 89 Pontiac Turbo Trans Am 25-544! Believe it or not this car takes a different filter than the Turbo Regals and has a wider base. This is a short filter like the 25-545.

These filters DO have an anti-drainback valve!

Made in the USA about 5 miles from us! This company has been making oil filters for more than three decades! This is the first major design change they have ever made. Eliminates the separate base and adds cooling fins. Same high quality.

LONG SPIN-ON OIL FILTERS are 6-1/4" long, 3-1/4" in diameter with 18 mm thread and standard o ring and accepts a 4-5/8" high 8 micron element.

Concerned that the longer filter will hit your Precision Stock Location Intercooler? We have a shorter filter that will work for you below.

SHORT SPIN-ON OIL FILTERS are 4-1/4" long, 3-1/4" in diameter with 18 mm thread and standard o ring and accepts a 4-5/8" high 8 micron element.

SHORT SPIN-ON OIL FILTERS for the 89 Pontiac Turbo Trans AM are 4-1/4" long, 3-1/4" in diameter body with 13/16"-16 thread and standard o ring and accepts a 4-5/8" high 8 micron element.

Questions Most Asked
These filters were developed to better protect expensive racing engines. A filter was needed that would handle a continuous high flow of oil while filtering out small particles. The flow should not be restrictive even when the filter is partially contaminated and all the oil should be filtered all the time. The element should not be affected by moisture which erodes paper elements, and it should withstand pressure surges without collapsing or rupturing. The filter element meets these requirements and overcome the shortcomings of conventional filters. In the years since their development these elements have proven themselves in NASCAR, SCCA, IMCA, IRL, and NHRA racing and on countless street miles. Conventional spin on filters have an element made from porous material (usually paper) which catches contaminant’s on its surface. The flow limitations of this design require a compromise between large pores for more flow, which also lets bigger particles through all the time or a bypass which lets unfiltered oil during times of high flow. When designing the filter this compromise was eliminated by going to depth filtration, where oil flows through millions of intertwined passages and contaminant’s are caught within the element. The flow characteristics of this design allows for finer filtration with greater flow without the need for a bypass. The synthetic fiber element material which is moisture resistant is sandwiched between two steel cages for surge protection. These elements filter out particles down to 8 microns, half the size of what the average spin-on filter does and has a flow rate even when contaminated, that is far greater than that required by any automotive application. Depth filtration extends filter element life because it can catch far more contaminates without restricting flow. Because of it’s longevity these filters are a natural match for use with the longer lasting synthetic oils. Lightweight aluminum remote canister housings are available for both the 2 5/8" tall and the 4 5/8" tall elements. While these styles have been most popular in racing, they are a good option for applications where a conventional spin-on is in a hard to access place. CM spin-on housings are offered for both the 2 5/8" tall and the 4 5/8" tall elements with thread and o-ring combinations that fits most engines. These machined aluminum housings will last the life of your car. The technology in the automotive area has advanced greatly in the past years. Today’s engines develop more horsepower from smaller displacements, they rotate at higher R.P.M.s, with tighter tolerances, and generally run hotter. To maintain longevity under these conditions engines require a strong lubrication system. Today’s oils have also improved to meet these demands, by lasting longer, and lubricating better, but even the best oil can only provide protection if it is kept clean. In an automotive engine, oil collects contaminates as it circulates through the engine, these particles should then be removed by the oil filter. Contaminant’s are present in all engines.They are a by-product of the combustion process which leaks past the piston rings. They are small particles of materials caused by the wearing of internal parts. Hot spots within an engine can cause oil decay (sludge) that needs to be removed. To be truly effective an oil filter needs to filter all the oil that goes through the lubrication system and remove these particles. Depth filtration removes more particles without restricting flow, providing the absolute protection needed.
*Can you clean Synthetic Filter Elements?*
No. Elements can not be cleaned because they work on depth filtration design where particles are caught within millions of tiny passages which run through out the element. This design allows for a much greater flow and the ability to hold far more particles than a conventional surface filter.
*When should I change my filter element?*
Under normal operating conditions we recommend a filter element should be changed every 10,000 street miles. Many customers change the element every second oil change. Under circumstances when large quantities of particles are being caught, like in older engines, engines which have not had regular oil changes, new engines during break-in, or when some oil additives are used, the element may need to be changed sooner. When the normal operating oil pressure has decreased 4 lbs. to 5 lbs. the filter should be changed.
*How often do I change the O-ring seals?*
Unless they are damaged they can last at least 4 filter changes.
*Do these Spin-on Filters have an anti-drain back valve?*
Yes. A flapper valve allows oil to easily enter the filter, while preventing it from draining out once the engine is shut off.
*Do the filters have a built-in bypass?*
No. The high flow of the element can handle more flow than that required by any automotive application, so all the oil can be filtered all the time.
