The 4P Ported High Flow Oil Pump for your K20C1 Type R, Accord, or Integra has been carefully developed after years of on-track development in 4P K20C1 racing engines.  Engines for racing applications are built with different tolerances and operated at high temperature under full load. RPM capabilities are increased dramatically in 4P race engines and the need for a better performing oil system is critical. These changes in the operating environment and how the engines are assembled require the oil pump to flow much better than OEM to maintain the pressures required to protect your engine.

The 4P oil pump increases the flow rate by more than 10% and eliminates cavitation and aeration in your oil as you begin to increase your engine speed beyond 8000 rpm.

These pumps are great for your track day car, dedicated street car, and are perfectly suitable for your everyday street car. This part is cheap insurance to protect your multi-thousand dollar investment. You can depend on the 4P name and their relentless pursuit to produce the world's best engines. They bring decades of experience in perfecting Honda oiling systems as seen with their world renowned K20 and B-Series oil systems that have allowed racers to maintain oil pressure to beyond 12,000 rpm without cavitation and while maintaining constant pressure through the entire RPM range. That same expertise has been applied to their K20C1 Ported High Flow pump in their racing engines since their release and is now available to everyone.

Application:

  • K20C Type R
  • K20C Accord
  • K20C Integra
  • Upgrade for Honda TC and TCR

reliable filters at a great price
Pattern Name: 16x20x1, Style: Merv 8
I've been using these Amazon Basics air filters for a while now, and they've been a great value. They fit perfectly, are easy to install, and do a good job of trapping dust, pollen, and other airborne particles. Since switching to these filters, I've noticed less dust around the house and my HVAC system seems to run efficiently. The MERV 8 rating provides solid everyday filtration without restricting airflow.

Amazon Basics MERV 11 Filters: Solid Performance Without the Premium Price
Pattern Name: 20x20x1, Style: Merv 11
Amazon Basics MERV 11 Filters: Solid Performance Without the Premium Price I’ve been using these Amazon Basics 20x20x1 MERV 11 filters in my home HVAC system, and overall they’ve been a very dependable option for routine filter changes. I like buying them in a 6-pack because it takes the hassle out of remembering to reorder every couple of months, and the per-filter cost is noticeably lower than the big-name brands at the hardware store. Installation is straightforward. The actual size fits my return slot properly with no bending or forcing, and airflow has remained strong. With MERV 11, these strike a nice balance for my setup — noticeably better dust and pollen capture than basic MERV 5 or 8 filters, but without putting obvious strain on the system. After about a month of use, the filters clearly show they’re doing their job, collecting a visible layer of dust and fine debris. A few things to keep in mind. The cardboard frame isn’t as rigid as some premium filters, and they’re a bit thinner than brands like Filtrete. They’ve held up fine for me during normal use, but I wouldn’t try to stretch them much past the recommended replacement interval. Also, if you have an older or low-powered HVAC system, MERV 11 may be more filtration than you need — in that case, a lower MERV option might make more sense. Bottom line: These Amazon Basics MERV 11 filters are a practical, budget-friendly choice that deliver solid filtration and good airflow for regular HVAC maintenance, as long as you stick to timely replacements and don’t expect premium-brand rigidity.

⭐️⭐️⭐️⭐️⭐️ I can breathe again — and my house says thank you 😂
Pattern Name: 20x20x1, Style: Merv 11
⭐️⭐️⭐️⭐️⭐️ I can breathe again — and my house says thank you 😂 These Amazon Basics MERV 11 air filters have been a game changer for my HVAC system. I installed them and immediately felt like my home went from “dust tornado aftermath” to “spa-day air vibes.” Whether it’s pollen, pet hair, or mystery dust bunnies lingering in the corners, these filters make the air feel noticeably cleaner and fresher. Installation was about as easy as ripping plastic wrap off a new gadget — pop out the old filter, slide these in, and suddenly the air quality goes from “huh?” to “ahhh.” The electrostatic pleated design grabs everything from sneaky dust motes to pet dander like a champ, and I can actually tell when the AC kicks on that the air feels crisper — in a good way. 🌬️ Between the six count and the solid MERV rating, this was a smart purchase that keeps my HVAC happy and my allergies way more manageable. If you want clean air without the hassle, these filters are a fantastic value and really get the job done. Highly recommend!

Good, I think.
Pattern Name: 16x25x1, Style: Merv 11
Not my area of expertise but wanted something with a thicker filter and these seem to be doing well. They last 3+ months before discoloration is noticeable to the point you’d think it’s time to put in a new filter. The 6-pack price can’t be beat, truly. Easily installed and used, fits perfect to size and looks clean. Unknown relief on allergies so far since it’s been winter but I’m optimistic.
