I hear all the time people listing Bosch platinum 4 spark plugs, if I understand correctly these have the 4 contact points. My question is, honestly is there a difference between these and let's say the single contact Bosch? (Performance-wise)
My mechanic has owned several e30's, certified by bmw and claims that there is no difference. I have been trying to upgrade as much as my car I can while keeping the original classic look of the car. I upgraded to Conforti chip, Bilsteins and Zimmerman drilled rotors and I am a believer for the suspension/brake upgrade. I like the bottle cap chrome wheels, large bumper, and etc.. so I don't think I'll get the larger wheels , it just doesn't look right to me, must be the affinity towards the original look of the car. My next upgrade will be the UUC short shifter, since I think that the gymbal/mount in my current stock shifter is worn and scratched up, and possibly the strut brace (front) Does this upgrade result in a dramatic difference? Also the K/N filter, which there are 2 versions, one fits the standard rectangular box while the other is the kind that needs the heatshield. I like the fact that they are washable. Is the difference apparent with the K/N upgrade?
Also I was informed that synthetic oil is not so good for these cars since the engines are older and the lubricants in the synthetic oil are smaller so they can leak through very small openings throughout the engine gradually.

. New plugs feel great because your engines computer doesn't have to compensate and instead is free to run like it used to when it was new.
. In other news just always replace your plugs and wires less than 100k miles its best to keep it safe. I used to have a big leak on my vehicle with 180k miles and what I used for a temp fix was a thicker oil instead of my usual 10W-30 and it was a good temp. fix ![[thumb]](/images/smilies/icon_smile_thumb.gif "Thumbs Up [thumb]"){kind=icon}
