Show original supplier description
The Ramair RPF-1391 is a high-performance replacement panel air filter engineered to fit the Mazda MX-5 NB mk2, directly replacing the less efficient OEM paper filter. The filter's construction includes a robust stainless steel cage support structure, borrowed from motorsport applications, and a rubber polymer surround for a clean finish and longevity. This filter is MAF safe and features a lifetime washable design, allowing for easy maintenance and a reduced environmental impact. Unlike many performance filters, this Ramair unit is completely oil-free, eliminating the risk of oil contamination to the Mass Air Flow sensor, which can cause performance issues. The filter measures 259mm in length and 164mm in width, with a unique shape to ensure a precise fit within the original airbox. Installation is straightforward, as it is designed as a direct OEM replacement. This specific item is not available for delivery to all regions; the provided evidence indicates it is not available in the user's country (XX).
