The stock MX5 breather system works well, and at low rpm and partial throttle conditions, it pulls a vacuum to reduce crankcase windage. The downside to this factory solution is that it recirculates all of the oil vapors directly into the inlet manifold, this reduces the effective octane rating of your fuel and reduces the performance of your engine.
The DaveFab dedicated MX5 Catch Can is designed to fit perfectly in the engine bay and is supplied with 1.5m of hose and clips for a neat install. The internal baffle separates suspended oil vapors and allows them to be collected preventing oily intakes.
The Catch Can bolts to the existing mounting holes in place of the factory Charcoal Canister.
