Genuine Mazda EGR Valve Gasket • LF01-28-305

Genuine Mazda LF01-28-305 EGR Valve Gasket

Replacement Genuine Mazda EGR valve gasket for Mazda MX-5 Mk3, Mk3.5 and Mk3.75 / NC models fitted with the 1.8L or 2.0L petrol engine from 2005/2006 to 2015 listed in the compatibility table.

The gasket seals the joint between the exhaust gas recirculation valve and its adjoining mounting surface. It helps prevent exhaust-gas leakage while maintaining the intended flow path through the EGR system.

A reliable EGR-system seal is important for preventing hot exhaust gases, soot and fumes from escaping around the valve connection. It also helps the EGR system operate as intended by maintaining a sealed exhaust-gas path.

This listing supplies one Genuine Mazda EGR valve gasket. One gasket is normally required per EGR valve installation.

Replacement is recommended whenever the EGR valve is removed. The original gasket can become compressed, heat-damaged, distorted or bonded to the mounting surface and may not reseal reliably once disturbed.

Possible signs of a failed gasket include exhaust-gas noise around the EGR valve, soot deposits at the joint, exhaust smells within the engine bay, reduced EGR performance or associated engine-management fault codes.

Fitment advice: Confirm that the vehicle retains the original EGR valve and mounting arrangement. Compare the replacement gasket shape, fixing-hole positions and gas passage with the removed component before installation.

Other items to consider: When changing this part, you may also want to consider purchasing the EGR valve, adjoining EGR pipe gaskets, EGR mounting bolts, intake-system gaskets and suitable cleaning products for removing carbon deposits from reusable EGR components.

Useful tools / consumables: Socket set, extension bars, calibrated torque wrench, plastic or non-damaging gasket scraper, penetrating fluid, EGR or intake-system cleaner, workshop vacuum and protective gloves.

Difficulty guide: DIY Difficulty: Moderate. Access varies according to the engine and surrounding components. EGR fasteners can be exposed to significant heat and corrosion, so care is required to avoid damaging the valve, pipework or adjoining mounting surfaces.

Why Genuine Mazda? Genuine Mazda gaskets are manufactured to the intended profile, material, thickness and fixing-hole positions. Using the correct OE gasket helps maintain a reliable seal and compatibility with the original Mazda EGR valve and mounting surfaces.

What’s in the box: One Genuine Mazda EGR valve gasket, part number LF01-28-305. The EGR valve, mounting bolts, pipework and additional gaskets are not included unless specifically shown or stated separately.

Installation notes: Allow the engine and exhaust components to cool fully before beginning work. Remove all remains of the original gasket without scratching the sealing surfaces. Clean away carbon, corrosion and contamination, position the new gasket in the correct orientation and tighten the EGR fasteners evenly to the applicable Mazda specification. Check the joint for leakage after installation.
