want to find a free way to get a couple more horsepower out of the 09 fit?
if you have a 09 fit, open the hood and right next to the master is the air intake. it you look right above the small hole where the air goes into the air box you will see a panel with 2 8mm bolts. take the 2 bolts off and the panel lifts right up. this is now whare the air is taken from. so instead of the stock lil like quarter sized hole now you have a 4 x 4 " intake. dont worry it will still pass through the filter so it will not damage the engine or trip and M.A.F codes. works( sounds a lil louder than usual ), and is cheaper than buying an intake
