These very popular mesh/screen style filters are hand made in the US and comprise of 3 layers of stainless steel mesh that filter down to an excellent level, with little compromise on air flow. They are an oil free design and are excellent in limited space applications. They have a groove moulded into the silicone fitting that sits tightly on the end of the ram tube. Made to specifications of Genuine Weber Ram tubes.
We have tested these filters on several engine dynos with very good results. Compared to open ran tubes, for every 100hp, the average loss in power was less than 0.25hp. Some engines have even seen gains in bottom-mid range torque with these.
