Genuine Mazda Engine Oil Filter – MX-5 Mk3 / NC • SH01-14-302A

Genuine Mazda SH01-14-302A Engine Oil Filter

Replacement Genuine Mazda spin-on engine oil filter for Mazda MX-5 Mk3, Mk3.5 and Mk3.75 / NC models with applicable 1.8L and 2.0L petrol engines listed in the compatibility table.

The filter removes metallic wear particles, combustion residue and other contaminants from the circulating engine oil before the lubricant reaches critical internal engine components.

Clean, correctly filtered oil helps protect the crankshaft bearings, connecting-rod bearings, camshafts, timing-chain system and other lubricated surfaces against premature wear.

The oil filter should normally be renewed during every engine-oil service because the internal filter media gradually accumulates contamination during normal engine operation.

This listing supplies one Genuine Mazda spin-on oil filter with an integral sealing ring, which is the quantity required per applicable engine.

• Unknown oil and filter service history

Fitment advice: This filter is used on the applicable Mazda MX-5 NC 1.8L and 2.0L petrol engines. SH01-14-302A is also used as a consolidated replacement filter across several other Mazda applications.

Reference advice: Mazda associates SH01-14-302A with several earlier oil-filter references, including SHY1-14-302, LF10-14-302, LF8J-14-302, LF05-14-302A, LF05-14-302B and LFY1-14-302. Genuine Mazda packaging may therefore display the current replacement number rather than the number originally fitted to the vehicle.

Service advice: Replace the oil filter whenever the engine oil is changed. Installing fresh oil while retaining a contaminated filter can immediately recirculate retained debris into the new lubricant.

Oil advice: Refill the engine with oil of the viscosity, specification and quantity required for the applicable engine and operating conditions.

Sealing-ring advice: Confirm that the old filter sealing ring has been removed from the engine mounting face. Installing the new filter over a retained seal can cause rapid and severe engine-oil loss.

Installation advice: Lightly lubricate the new filter sealing ring with clean engine oil. Screw the filter onto the mounting point by hand until the seal contacts the mounting face, then tighten according to the applicable Mazda procedure or the instructions printed on the filter.

Overtightening advice: Do not excessively tighten the filter. Overtightening can damage the sealing ring, filter casing or mounting thread and may make removal difficult at the next service.

Oil-pressure advice: After installation, start the engine and confirm that the oil-pressure warning lamp extinguishes promptly. Switch off immediately and investigate if the warning remains illuminated.

Leak inspection: Inspect the oil-filter and sump-plug areas for leakage while the engine is running and again after the engine has been switched off.

Oil-level advice: Allow the oil to settle after the initial start-up, then recheck the dipstick and correct the level as required. Filling the new oil filter may slightly reduce the measured sump level.

Other items to consider: Consider purchasing the correct quantity of engine oil and a new sump-plug sealing washer for a complete oil service.

Useful tools / consumables: Suitable oil-filter removal tool, socket and torque wrench for the sump plug, drain container, funnel, protective gloves, cleaning cloths and the correct engine oil.

Difficulty guide: DIY Difficulty: Easy to moderate. Safe vehicle support, suitable handling and disposal of used oil, correct filter installation and careful confirmation of the final oil level are required.

Why Genuine Mazda? Genuine Mazda oil filters are specified for the intended mounting thread, sealing face, filter-media performance, flow rate and lubrication-system pressure requirements. Using the correct OE filter helps maintain reliable oil circulation and compatibility with the original engine.

What’s in the box: One Genuine Mazda spin-on engine oil filter with integral sealing ring, part number SH01-14-302A. Engine oil, sump-plug washer, tools and cleaning materials are not included unless specifically shown or stated separately.

Installation notes: Warm the engine sufficiently to allow the oil to drain, then switch it off and safely support the vehicle. Drain the used oil, remove the original filter and clean the mounting face. Confirm that the old sealing ring has not remained attached. Lubricate the new seal with clean oil, install the filter by hand and tighten as specified. Refit the sump plug with a suitable new sealing washer, refill the engine, start it briefly and check for leaks. Switch off, allow the oil to settle and confirm the final dipstick level.
