A slight performance upgrade for the distributor cap/spark plugs.



NGK V Gold Palladium for a hotter burning plug
*disadvantage - you go through plugs faster*


Before (NGK plug also) / After

Distributor cap



Take wrench (don't remember size), locate a bolt under the distributor cap and loosen it. Grap a hold of you (red) cap and twist clock wise (forward) about a 1/2 inch (or as far as it will go, depends on your car), then tighten the bolt back up and release cap. (note that you need to keep one hand on the distributor cap, and one on the wrench to tighten). This will cause the car to spark hotter, and the car to burn fuel better.

doesn't that advance the timing? or slow it down? isn't that really really bad to turn the distributer either foward or backwards? anyone else have input on this before i try it?

do you do it with the car running or off?

its main function is to make the spark plug burn hotter and combust the fuel better. In my case, my distributor cap only moved maybe a half and inch. and i don't think it messes with timing.

i got the idea from a guy that works on my saab, so i don't think he would put my car in any harm.

i'd recommend doing it while the car is off :wink:

how long have you been driving around with it like this? how many miles?

what year is your car, and how many miles, and i assume you have no turbo?

so all i do is losen the little nut, and twist it a half inch or as far foward as it can go(which ever comes first), and you and by foward, you mean the top towards me, in other words, if you are standing on the drivers side of the car, looking at the cap, meanging the door is to your left, and headlight to your right, that you rotate the top of the cap towards the headlight, also known as counterclockwise, right?

what happens if i rotate it the wrong way, not saying i'm stupid, but what happens if i do it wrong.

it's a 1998 900s N/A with about 91k on it. :wink:

k, i guess i made that sound complecated, just turn it clockwise. and as far as it goes. not towards the headlight, towards the driver. i thought i said clockwise up there...

i don't know what will happen if it goes to far, probably your car won't turn over??

so if you were standing in front of the car, and your thumb was on top of the cap you would rotate the thumb to the back of the car?

Hi

I would be interested to hear other views on the distributor 'mod'. I run NGK Iridium plugs (BCP5EV-X) and the car feels slightly more responsive than on standard ones. They are relatively expensive as far as plugs go £18 (circa 30USD) from a cheap autofactor...eurocarparts.co.uk. Robbery from main stealer.

Not heard of the Palladium plugs. Anyone running those?? I'll check the website.
Cheers
Al

whoa i didnt see this one before...where do i begin...

ok first off what youre doing here is advancing the timing, this can make more power, however it can also just make the car knock easier, potentially blowing the motor :roll: . now it probably wont blow the motor since i think the cars computer can pull back the timing if it senses knock. so then why would you bother doing this mod if the computer is just going to bring you back to whatever timing that youre supposed to have in the first place? well hell i dont know :? .

oh and when youre adjusting timing its a really good idea to use a timing light, since as i said if the timing is too advanced then the motor blows, if its too low you get shitty gass mileage and the car doesnt run right, or wont start at all. might wanna look into how a cars ignition system works before you start rotating your distributor at random :roll: . but hey, worst case scenario you blow the motor, get rid of the n/a and buy a turbo :wink: .

there is no need to advance the timing on an n/a, the EZK ignition will simply pull it back once the RPM's come up due to knock, at which point you will get WORSE performance than you would with the timing set to standard. I second what paul said, you should not go "playing" with your cars ignition timing if you have no idea what you are doing. If you advanced the timing about 2 degrees (you would need a timing light to do this properly) you might get about 1/4 second off your 0-60 time, any more than that, EZK will back off your timing and you will be in worse shape than you would be stock. if you want better performance, do something worthwile... playing with ignition timing is not the way to do it...
