Push your K-series to the limit, without fear of oil starvation!

Meet the 4P Ported K-Series Oil Pump — the upgrade your build needs to stay reliable past 9,000 rpm. The factory pump is great… until it isn’t. At higher revs and elevated temps, cavitation and pressure drop become the enemy. That’s where 4P steps in.

🔧 Why choose the 4P pump?
+25% increased oil flow compared to stock — designed to handle continuous use above 9,000 rpm
Tested up to 12,000 rpm
Fits all K20 / K24 engines (yes, including K20Z3)
Slight gains in power: optimized pickup location (deeper and more forward) frees up ~1–2 hp
Installation kits available (oil chain, guide, windage tray, notched for K24 fitment)

Black-belt “insurance” for your multi-thousand dollar engine build

4P K-Series Valve Springs are made from the highest quality spring wire and paired with premium titanium retainers, precision machined in-house on our Mazak 9-axis Swiss lathe.

We hold ourselves to the highest quality standards because valvetrain reliability is critical when you’re pushing the limits. Every component is engineered for maximum durability, consistent performance, and the confidence to turn the RPM your engine was built for.

Quality isn’t an accident. It’s built into every part we make.
