Product Overview
ITG ProFilter WB-446 – Mazda MX-5 ND (2015 onwards) and Fiat 124 Spider
The ND MX-5 is a car built around driver involvement, and the ITG ProFilter WB-446 is a simple way to replace the throwaway paper element in its air box with something you can keep. ITG lists it for the MX-5 ND with the 1.5 (131 bhp) and 2.0 (160 bhp) Skyactiv-G engines from 2015, and for the Fiat 124 Spider and Abarth 124 with the 1.4 turbo from 2016. It is hand-made in Britain from multi-layer reticulated foam.
Benefits over a paper element
Foam captures dirt through its depth rather than on a thin surface, so it holds more before airflow suffers. It also tolerates the heat cycles and dusty paddocks of track days and can be cleaned and re-oiled instead of replaced.
- Direct replacement for the OE panel – no cutting or new ducting
- Keeps the standard air box and sensors
- Washable and reusable foam media
- Hand-built in the UK by ITG
Specifications
The WB-446 is a rectangular panel measuring 342 x 142 mm. Full application details are on the ITG ProFilter WB-446 page for the MX-5 ND.
Fitting
Release the air box lid clips, lift out the paper element and clean any debris from the lower housing. Place the ProFilter so the foam edge seats evenly all the way round, then refit the lid and clips, taking care not to pinch the foam. The filter must stay oiled to work properly, so when it gets dirty wash it with ITG cleaner, let it dry naturally and re-oil it before refitting. Earlier NA, NB and NC MX-5 models use different ITG filters, so check your generation before ordering.
