RIDEX Engine Oil Filter – MX-5 Mk1 NA / Mk2 NB / Mk4 ND • 7O0026

RIDEX Engine Oil Filter – 7O0026

Replacement spin-on engine oil filter for Mazda MX-5 Mk1 / NA 1.6 and 1.8, Mk2 / NB and Mk2.5 / NB-FL 1.6 and 1.8, plus selected Mk4 / ND petrol models, designed to remove contaminants from circulating engine oil and support reliable engine lubrication.

The engine oil filter is an essential component of the vehicle's lubrication system, helping remove contaminants carried by engine oil before they continue circulating through vital internal engine components.

During normal engine operation, oil lubricates moving components such as the crankshaft, connecting rod bearings, camshafts and other moving engine parts. As it circulates, the oil can collect wear particles, carbon deposits and other unwanted contaminants.

RIDEX 7O0026 contains filtration media designed to capture these contaminants, helping maintain cleaner engine oil and protect the components that depend on a consistent supply of lubrication.

The filter uses a conventional spin-on design, combining the filter element and housing into a single replaceable unit for convenient routine servicing.

With a 65.5mm body diameter, 66.5mm height and M20 × 1.5 mounting thread, the filter is designed for the corresponding Mazda petrol engine oil filter mounting.

The filter incorporates an anti-return valve, which helps limit oil draining back out of the filter when the engine is switched off.

An internal overflow valve provides an alternative flow path when the filter media creates excessive restriction, helping maintain engine oil circulation under demanding operating conditions.

As an oil filter accumulates trapped contamination during normal use, its filtration capacity gradually reduces. Replacing the filter during routine engine oil servicing helps maintain the lubrication system's intended performance.

RIDEX 7O0026 is suitable for Mazda MX-5 Mk1 / NA and Mk2 / NB petrol engine applications, including the later NB-FL models, together with selected Mazda MX-5 Mk4 / ND engines using the corresponding filter specification.

It offers a practical replacement for engine servicing, scheduled oil changes and engine maintenance.

What's in the Box: 1x RIDEX 7O0026 Spin-On Engine Oil Filter, complete with fitted sealing gasket.

Installation / Service Notes: Follow the applicable Mazda engine oil and filter servicing procedure. Park the vehicle on a level surface and allow the engine to cool sufficiently before beginning work. Safely raise and support the vehicle if underbody access is required. Drain the used engine oil into a suitable container and remove the existing oil filter using an appropriate filter removal tool. Ensure that the previous filter's sealing gasket has been removed from the engine mounting surface and clean the mounting area thoroughly. Lightly lubricate the new filter sealing gasket with clean engine oil. Screw the replacement RIDEX oil filter onto the mounting until the gasket contacts the sealing surface, then tighten according to the appropriate installation instructions. Avoid overtightening the filter. Refit the sump drain plug with a suitable sealing washer and tighten it to the specified torque. Refill the engine with the correct grade and quantity of fresh engine oil. Start the engine and inspect the filter and sump drain plug for leakage. Switch off the engine, allow the oil to settle and check the oil level, topping up as necessary. Dispose of the used oil and filter through an appropriate recycling or waste collection facility.
