Made using two sliding tubes, this is a high quality semi waterproof air filter suitable for all 1/8th scale Nitro engines. It contains both coarse and fine foam, to ensure the engine air is good quality.
This is obviously not totally waterproof as the engine still needs to breathe, but it is ideal for running through puddles, or on the beach etc.
This filter has two foam elements. The outer element filters heavy dust particles and larger debris, whilst the inner foam is much finer and filters small particles ensuring you engine inhales clean air.
The filter oil is specially formulated by Optifuel, and has been designed to work with fine foam filters, allowing the engine to breath, but sticky enough to stop the smallest damaging dust particles.
The product will come with a plastic sealable bag. Simply put the foam and a few drops of filter oil in the bag and squeeze away! this will give you a nicely oiled filter without getting your figers dirty!.
