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.

Ok So BOSCH has 4 tips right? ->> I will call these Ground Tips

Ordinary plugs that were first created had only 1 Ground Tip.

Well the Theory why BOSCH performs so bad in HIGH performance engines / Import engines is that the 4 Ground tips actually block out most of the gas and air that is shooting up the cylinders when the piston is going up.

PLUS the way the Iridium tip of the BOSCH plug is designed is that it’s actually enclosed within a barrier that is heat resistant and electrical insulated to prevent accidental grounding. (Hence the white barrier surrounding on the tiny metal spark tip).
This spark tip is so small that it has a very hard time in transferring the electrical currents to the 4 ground points (if 1 couldn’t do it why 4?). Not only is the Plug easily fouled by a high concentration of GAS and AIR mixture. It is trapped in between the 4 tips making it harder to spark, as GAS and AIR is moving. In a 1 Tip design GAS and Air is trapped only by 1 side so therefore it can escape the to other sides making it easier to ignite the cylinder.

The 4 ground tips provide multiple signals to ground which weakens the charge of electricity because the spike from the spark tip would flow either to 1, 2 ,3 or all 4 ground tips which lessons the power to combust an cylinder. --> This results in a weak spark.
It’s really Quality not Quantity. A single tip would produce a powerful spike and ignite the cylinder. There would only be 1 way to get to ground and all that energy must take that route.
Its as simple as choosing 4 paths to take and fighitng over it which goes to the same place or 1 path which forces everyone to the place.

This is just my Theory and It hasn’t even been tested yet, but a simulation or something would prove it quite right since BOSCH sucks anyway.

Diagrams and Photos soon to come when Im free in time.

Whats better? NGK Plugs or the Denso Iridiums,coz i have the denso's in my car..looking to get NGKs now since everyones been hyping them up so much..but don't really know how much of a difference they will make..

cheers lads..

I like the Densos they look rather aggressive with the super sharp pointy Iridium tip. Overall I haven't gotten into much problems with the Densos nor the NGK's so anything would be fine as long as its these two.

Denso's do have Japanese writing all over them....Intresting
