K&N HS4/H4/HIF38 1.5" CONE AIR FILTER

For 1.5" carb applications, this Conical K&N filter is the answer. Fits single or dual carb setups. Sold individually. K & N airfilters are unsurpassed in performance yet are compact in size to fit in even the most cramped quarters. These do not seem to work very well on small bore engines and upto 6bhp loss has been recorded so we recommend the K&N element in the case for this purpose which will increase BHP.
