Introduction: The Evolution of Oil Filtration in High-Performance Engines

Oil filters are not just components—they’re the gatekeepers of engine longevity and power delivery. For racers, tuners, and automotive enthusiasts who push their engines to the limit, choosing the right oil filter is crucial. The Costa Oil Racing Filter COF4622 – COF22000 is specifically designed to exceed the demands of high-output engines, delivering superior performance compared to mainstream filters like the Fram PH6607.

In this article, we’ll break down the science, specs, and performance metrics that make Costa Oil’s COF4622 – COF22000 the gold standard for racing applications—and why it vastly outperforms the Fram PH6607 in every measurable category.

Side-by-Side Specs Comparison: COF4622 – COF22000 vs Fram PH6607

---

Superior Filtration Technology: Engineered for High RPM Protection

The Costa Oil Racing Filter COF4622 – COF22000 is constructed with multi-layer synthetic glass-blend media, offering exceptionally low restriction and high debris holding capacity. Unlike the Fram PH6607, which uses a cellulose-based blend more appropriate for commuter vehicles, the COF22000 is optimized for:

• High-viscosity racing oils

• Extended drain intervals

• Micron-level contaminant removal

The COF4622’s 99% efficiency at 20 microns means it captures harmful particulates before they can circulate back into the engine, reducing premature wear on camshafts, bearings, and lifters under sustained high-load conditions.

Flow Rate & Pressure Drop: Crucial for Peak Engine Output

• 

• essure drop = More oil reaching the bearings

A major shortcoming of mainstream filters like the Fram PH6607 is the pressure drop across the filter media during high-flow conditions. The COF4622 is flow-tested to handle 15-18 gallons per minute, with minimal restriction, making it ideal for high-output engines that operate at 5,000+ RPM for prolonged periods.

Why it matters:

• Less prHigh flow = Better cooling and lubrication

• Consistent pressure = Stable VVT and turbo performance

Anti-Drainback Valve: Silicone vs. Nitrile

Hot starts kill engines—and oil filters with cheap nitrile anti-drainback valves are part of the problem. The Costa Oil COF4622 features a high-temp silicone anti-drainback valve that retains flexibility and seal integrity above 300°F. This ensures immediate oil pressure at startup, even in racing or turbocharged applications where oil temperatures can spike rapidly.

By contrast, the Fram PH6607 uses nitrile rubber, which becomes brittle and leaks over time—especially in vehicles that experience high-temperature cycling or extended storage between races.

---

Bypass Valve PSI: Tuned for Racing Oil Pressure

The 22 PSI bypass valve in the COF22000 is calibrated for racing environments, ensuring that the filter does not bypass during sudden surges in oil pressure—keeping dirty oil from re-entering the engine during high-RPM runs.

The Fram PH6607 opens at just 12-15 PSI, meaning more unfiltered oil can bypass the media during high-load events like cold starts, dyno pulls, or full-throttle acceleration.

---

Durability & Build Quality: Made to Withstand the Track

• Steel-backed end caps

• Double-layer center tube for added rigidity

• Laser-welded seams

• 300+ PSI burst strength

These features make the COF4622 far more durable than consumer-grade filters like the Fram PH6607, which rely on stamped components, crimped seams, and less robust canister walls.

When used with high-performance full synthetic oil such as Costa Oil 5W-30 Racing Blend, the COF4622 offers unmatched stability even under the most brutal track conditions.

---

Fitment & Compatibility

The COF4622 – COF22000 is a direct fit replacement for vehicles that use:

• Honda Civic (Si, Type R)

• Acura RSX, Integra

• Nissan 350Z, 370Z

• Mitsubishi Lancer Evo

• Various Subaru EJ-series engines

If your vehicle uses a M20 x 1.5mm thread and a 2.5-3.5” filter, you can upgrade immediately from the Fram PH6607 to the Costa COF4622 without adapters or modifications.

Who Should Use the COF4622?

✅ Weekend track warriors
✅ Full-time racers
✅ Tuners running boosted applications
✅ Engine builders needing higher oil system reliability
✅ Performance daily drivers with upgraded internals

Summary: Why Fram Just Doesn’t Cut It Anymore

While the Fram PH6607 may be sufficient for grocery-getters and mild stock engines, it simply isn’t engineered for high-performance demands. The Costa Oil COF4622 – COF22000, on the other hand, is a purpose-built racing oil filter that:

• Filters finer particles

• Handles higher pressure and temperature

• Flows more oil

• Protects better at startup and redline

• Lasts longer under racing stress

---

Final Verdict: Step Up to Costa Oil Racing Filters

If you’re still running a Fram PH6607 on your performance engine, it’s time to upgrade to a filter that’s as serious as your build. The Costa Oil Racing Filter COF4622 – COF22000 is the professional’s choice for ultimate protection and performance.
