Question Two Questions From a Newbie

I've got a 2001 2.5 RS that I'm just now getting around to "tricking" it out, and I've got a few questions:

I've seen ads online occasionally and a few e-bay listings for timing advance kits that consist of a resistor that is to be inserted into the intake air temp sensor line. First, where in that mess of cables on the throttle body/manifold is the IAT sensor? Second, does anyone have an idea of what the optimum resistance would be to put inline with the IAT?

Also, does anyone know what the reccomended spark plug gap is for the EJ25?

If you know, give me a shout!

i am also not a p****


if you do a search for sparkplug gap, you should find a few threads with the answer.

and for the advance timing kit, i thought our timing was already very advanced stock, so i wouldn't screw with that stuff.

Personally...and this is my opinion...I don't want to mess around with the computer systems on the car in a manner like that. Tacking on bits of electronics to try to fool the car without fully understanding what is happening isn't, in my mind, a good idea at all.

If I am going to mess with the electronics of the car I am going to get a device from a VERY reputable manufacturer so if there ever is any sort of problem I know who I can turn to. These little add on bits don't come from the most reliable of sources... And I want nothing but the best (that I can afford!) for my baby.

There's already a thread about that timing advancement kit. I'm not sure what they found out, but here's the link.
