A direct replacement air filter for the Honda Acty HA3 and HA4, manufactured in the UK by ITG Filters. Unlike the standard paper element, the ITG Trifoam filter uses a three-layer polyurethane foam construction that can be cleaned and re-oiled for repeated use — eliminating the need for a replacement filter at every service interval.
Tested back-to-back against a genuine Honda paper filter, the ITG unit delivered a measured gain of 0.9bhp, making it a straightforward upgrade with no modification required.
Each filter is supplied with a connecting stud for fitting directly into the OEM intake housing, ensuring a secure and hassle-free installation.
Key Features:
- Three-layer foam construction for high filtration efficiency
- Washable and re-oilable
- Direct OEM fit for Honda Acty HA3 and HA4 (1990–1999)
- Supplied with connecting stud for OEM intake housing fitment
- 0.9bhp improvement over a used genuine Honda filter in back-to-back testing and 0.2bhp improvement over the cotton style filter
- Manufactured in the UK by ITG Filters
