Engine Bay Rodent Guard Mesh (Automotive aftermarket) is used for closing the openings rodents use to get into engine bays, air boxes and cabin-filter housings, where they nest and chew soy-based wiring insulation.
Opening size: 6.4 mm (1/4 in) stops rats and most mice; 3.2 mm for juvenile mice.
Wire & alloy: SS304 welded mesh at 0.56–0.64 mm wire resists chewing; plastic or aluminum screen does not.
Heat clearance: Keep PVC-coated mesh at least 100 mm from exhaust manifolds and turbochargers.
Materials
Standard supply is stainless steel 304; the material column in the table and the drawing options show the exact grade for each size. Other alloys and finishes can be quoted to your drawing.
Fitting & Care
Cut the mesh 20 mm oversize and fold the edges so there are no sharp wire ends near hoses.
Fix with stainless zip ties or the existing clips; check after every service that the guard was refitted.
Common Mistakes
Covering the cabin air intake with a mesh so fine that it restricts HVAC airflow.
Leaving the gap around the firewall grommets open, which is the route rodents take most often.
When Engine Bay Rodent Guard Mesh Is Not the Right Choice
Not a heat shield and not a substitute for removing nesting material or food sources around a parked vehicle.
Engine Bay Rodent Guard Mesh is made to order as finished parts. Indicative pricing starts from about US$4.50 per piece for a standard size at production quantity; the final price depends on size, material, finish, tooling and order volume.

Does stainless steel mesh stop rodents chewing car wiring?
Yes — rodents cannot chew through stainless welded mesh, so closing intake openings keeps them out of the bay.
What mesh opening keeps mice out of an engine bay?
About 6 mm stops rats and adult mice; use 3 mm where juvenile mice are a problem.
Where should rodent mesh be installed on a car?
Over the cabin air intake, air-box inlet and any large openings in the under-tray.
