Here is a guide to make a forced air induction kit for a 172/182Tools needA drillA pencilAnd a pair of scissorFirst u need to get hold a induction cone. I bought this pipercross one off a member on here for £15Need u need to go to any agricultural supplies shop and buy a 5 litre calf rearing bucket for £1.50, everywhere sells themNext make round the IK with a pencilNext drll a hole one cm from inside the circle drill a hole and then cut out a circle with your scissorsNext cut round the hole with your scissors up to the circle u marked with your pencilNow your bucket should look like thisNow pust the induction cone through the hole, it will be tight and the bucket will grab it and be very secureNow fit to the thottle body, the bucket fits perfectly into the 172 engine bayThis is a very simple mod that takes 20 minutes tops. Now u can enjoy the induction ROAR!! Without loosing any bhp as the bucket shields the filter from any heat soak.Feel quite chuffed i have invented this!!Comments welcome
