Product Details

The Melling M-55HV is a high volume oil pump designed to increase oil flow by approximately 20% compared to standard volume pumps, improving oil pressure at idle and throughout the engine's operating range. This enhanced flow rate makes it ideal for performance applications, engines with increased bearing clearances, or situations where additional oil pressure is needed.

Key Features:

  • High volume design delivers approximately 20% more oil flow than standard pumps
  • Precision-machined gears or gerotor assembly manufactured to tight tolerances for consistent pressure
  • Precision-ground end plates provide maximum wear resistance and durability
  • Engineered from high-quality materials for reliable, long-lasting performance
  • Individually pressure and flow tested under simulated engine operating conditions
  • Utilizes latest gear and gerotor technology for optimal efficiency

Melling is a trusted OE supplier with decades of experience in oil pump manufacturing. Each M-55HV pump is built to exacting standards and tested to ensure it meets strict quality and performance specifications before leaving the factory, providing dependable lubrication performance in demanding applications.

I ordered some mud flaps for my 2016 sti. They arrived way earlier than I thought they would.

Was good and fast

that was fast...best price.. plus NO tax.

Terrific website. Thanks very much!

Great place to shop, low prices and ease of website to browse!

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

Best price I can find on my item and fast shipping. Thinking about becoming a member to order all my parts for my racing team.

Had by far the cheapest place on the internet for the part I was looking for! Shipping was extremely fast as well! A++

All pieces ordered were shipped promptly and arrived in very great shape. I will be ordering from this site again.

Good prices. Good communication.
