The CSP Products air cleaner with the classic CSP Products logo is available in different versions and can be configured to your liking.

The billet aluminium CSP Products air cleaners solve multiple problems in one go. As opposed to tin housings, the CSP Products plates feature guides for the air filter inserts, preventing them from collapsing. Compared to other aluminium air filters, these are extremely light, yet sturdy, and take unwanted load off the manifold mounting holes. The air filter furthermore impress with details such as the two little eyelets, which can be used to hook up a return spring, easy assembly because of the tapered spacers with matching chamfer in the top covers, and different base plates for different carb sizes. And of course they always come with high-quality, washable cotton K&N filters! They measure 95 mm overall (with the 83 mm inlets) and 113 mm overall (with the 100 mm filters).
