I think the point Matt was getting at was you are probably not competent enough to complete the job. If you had been reading and researching you would not have bought the junk you have already. Your current mods were installed by a "professional"? Do yourself a favor and seek a different professional cause the air temp resistor pile of crap is probably doing more harm than good. If you need a pro to install a 1" spacer or auto zone special cai, you cant handle what you are thinking of doing.
