Product Details

The Prime Guard QUIK866340Q03 is an aftermarket replacement spin-on oil filter engineered to cross-reference OEM part number 866340Q03 for MerCruiser sterndrive and inboard engines. Designed for the demanding marine environment, this filter delivers reliable engine protection during every oil change interval.

Key Features:

  • Spin-on canister design for straightforward installation and removal
  • Anti-drain back valve helps ensure immediate lubrication at startup and prevents dry starts
  • High-efficiency filter media removes harmful contaminants and fine particles from engine oil
  • Heavy-duty metal shell construction with corrosion-resistant finish suited for saltwater and marine environments
  • Manufactured to meet fit, form, and function requirements per SAE and ISO test procedures

Compatibility: Fits MerCruiser sterndrive and inboard engines, including Mercury Marine-made 4.5L and 6.2L engines. Not intended for V6 engines with the oil filter mounted directly on the engine block.

Cross-Reference / OEM Part Number: 866340Q03, 35-866340Q03

Prime Guard filters are leak tested and built with quality components including a bypass valve, relief spring, support tube, anti-drain valve, sealing ring, and plastisol-sealed end caps with nitrile gaskets — delivering dependable protection for your marine engine season after season.

Great service!

Simple quick and easy

Great service and fast delivery service. Ill order from again. Thanks

Shipping was fast and received tires in a couple of days. Great prices also.

The only issue was the shipping straps on both shocks were broken on one end only! Made it more difficult to install! But for the price I can't complain much! Thanks

Just as described. Fast service

Good experience. My tires were exactly what I ordered and I got a great deal.

Great price
