Just to add to whats been said, you don't want to over oil it. just hit all areas quickly. It only needs very little and if you over oil it you can end up with more restriction than paper. And YES......leave the snorkel out ! Pulling mine gave the the biggest boost in power of all the things i've done. But remember that if it makes little difference it's only because the jetting needs to be upped. But it probably will anyways. this is assuming you have aftermarket pipes. If not, then i'm not sure whether it'll do much, tho i have heard of people with stock pipes getting a boost from it.
