Cold Air Intake Page 3

As for the air-filter, there is no need to shell out $50 to $100 for a K&N or Unifilter "race" filter as you can make one out of your old [and probably very overdue for replacement] genuine filter. The genuine filter is a crappy cardboard airfilter and would be an ideal filter for a vehicle travelling along dusty roads however as I rarely take the 2-fiddy cross country I went to a rubber outlet [Clarke Rubber, etc...] and asked for some "Automotive Polyeurethane" as that is what most race filters are made from. I removed the cardboard fins from the filter then cut some foam to fit. This material does need to be oiled though. 2-stroke oil is what they use to oil them, don't go buy "air-filter oil" as it's just over priced 2-stroke oil. Make sure you remove any excess oil. I cannot stress this enough. I did some research on the correct oiling techniques from K&N and they said, "Saturate the filter but dont wring it out. Dab the excess away with a rag."

DO NOT FOLLOW THAT ADVICE IF MAKING OUR OWN FILTER!!!
