http://www.radioshack.com/product/in...entPage=search

that should work, i believe...

and when you install a longtube header like that, the car will run rich at first...but i believe the top O2 sensor tells the computer that and retrains it, because it seemed to stop running rich after a while...

you will probably want to reset the car computer and reteach it everything after u put on the header and O2 cheater...it will make things run a little nicer for you

**after multiple months of using this cheater without any problems...the CEL came on with an error P0420...by the time i stopped somewhere to check everything, it stopped throwing the code but kept the light on...so i reset the computer a couple days ago and the light hasnt come back yet...im not sure why it decided to throw a code for that short amount of time, but all is well again**

^^awesome, i think ur the first other person to post that you did this as well...once again, my CEL came on...im guessing i have fried the resistor after being used for so long with very little heat protection and that close to the header...i think im going to have to take it apart and put on a new resistor..thankfully i still have the other 4 from the 5 pack radioshack gave me! haha...

it seems to run fine even with that check engine light on...but i think its reassuring to know that the computer thinks the catalytic converter is ok...

it probably doesnt actually change anything but i just like to make the computer happy, haha
