Tuneups- STAY away from Bosch, sparkplugs especially Options

[soulshadow]

Guys I just wanted to say that if you ever go to the auto part store and buy any spark plugs or filters and ETC.
Stay away from Bosch products (Minus the O2 sensor since we can't find anything else)

The worst spark Plugs you can ever, EVER buy are BOSCH platinums with the dumb looking 2,3,4 tips.
These are terrible, suck a55 and will bog down your engine like no tomorrow especially when going up hills and high end reviving.

I would explain my theory on these crappy a55 spark plugs but Don't want to bored you guys. So i will save my explai-nation.

BOSCH sucks at spark-plugs.

I put bosch +4's in my 7a and had positive results. The old plugs (I think NGK) had a small bit of fouling but not much. The new plugs made it idle and rev smoother (including high rpm) without any heat issues. My THEORY is that the spark in the +4's only grounds to one tip which would keep it from fouling longer than a regular plug but since I do not have any proof and haven't tested it i'm not going to make a claim that might be false . I can only speak for my st which doesn't have a high performance engine but I'm sure Bosch plugs aren't the absolute worst you can buy. Do the first 6gc diesel swap and you won't have to worry about it.
