BOSCH Super 4 Vs NGK Iridiums

[EddeyDancer]

Apart from the Price Tag, does anyone have any
Genuine Information to share, based on actual Experiences?

[Vxlgsi]

bosch super 4's are just long life plugs, having 4 electrodes just makes it harded for the fuel and air to get into the plug.

NKG platinums or iridiums are the ones to have.

standard vauxhall one's just as good and cheaper

They do the job and if you want ones like the super fours, 2.6 GSI vectras are the same plug as the Bosch super four and a lot cheaper on trade club

Eddy,
Ignore the trade club bit, just noticed you live down under,

I like the idea of Longer Life...

As changing the Rear Sparkies, is somewhat quite involving!

I don't have the Level of Skill to do that, neither do the Garages here!

***NGK IRIDIUM IX SPARK PLUGS***

ENHANCED IGNITION
The small diameter Iridium tip focuses the electrical energy
around the centre electrode, resulting in more efficient ignition.

BETTER ACCELERATION
Reduction of 0.7 seconds in time to accelerate from 20-60mph.

FASTER STARTING & SMOOTHER RUNNING
With the high ignitability of the NGK Iridium IX Spark Plug, your engine will
start up quickly and run smoothly even on cold and damp mornings.

LONGER LIFE
The 0.6mm Iridium electrode gives continuous reliability
over a long period.

BETTER FUEL CONSUMPTION
The excellent ignitability of NGK Iridium IX Spark Plugs gives
very high combustion efficiency, resulting in more miles per gallon.

***A Performance breakthrough from BOSCH...

The new Bosch Super-4 outperforms conventional spark plugs in every situation. It uses state-of-the-art 'surface-air-gap' technology, and features four thin ground electrodes with one pointed, silver-plated centre electrode. This enables the ignition spark to choose the best path for reliable ignition, and according to the load placed on the engine.

Advantages of fitting Super-4 Plugs to your engine:

Increased acceleration

Less chance of misfiring

Better cold starting performance

Greater spark power - Increased engine efficiency

Increased Acceleration: Air-fuel mixture deposits occur in driving primarily during heavy acceleration. The Super-4 spark plug from Bosch with increased ignition reliability prevents misfiring and therefore guarantees improved acceleration. In a trial, acceleration from 19 to 75 mph in third or fourth gear resulted in 0.4 s gain in each case. The acceleration distance decreased by five meters, providing driver and passengers with improved safety during overtaking.

Less chance of misfiring: Bosch 'surface-air gap' technology ensures a more even wear of the electrodes. This, in turn, leads to a more reliable spark. Since the probability of a spark choosing one of the eight possible paths is equal, wear on the ground electrodes is distributed evenly over all four electrodes.

Better cold starting performance: Thanks to the improved low-temperature behaviour and self-cleaning feature, up to three times as many cold starts are possible than with conventional spark plugs. Environmental protection and protection for the catalytic converter The improved cold start behaviour and increased ignition reliability even in the warm-up phase increases fuel combustion and thus reduces HC-emissions. This also has the effect of extending the service life of the catalytic converter.

Greater Spark Power: The spark in the Super 4 loses less power than the spark in a conventional spark plug due to the four thin ground electrodes (less resistance). Spark plug efficiency therefore increases because the air/fuel mixture has up to 40% more power available for every ignition.

So it weighs less!

It uses state-of-the-art 'surface-air-gap' technology

Wow. A spark gap!

and features four thin ground electrodes

Thin? Let's hope they don't brag that there's less resistance to ground later on then.

with one pointed, silver-plated centre electrode. This enables the ignition spark to choose the best path for reliable ignition, and according to the load placed on the engine.

A spark that knows what the "best" path is. Sweet. I can't help thinking that if it goes anywhere other than in the middle, something's seriously amiss.

"Eight possible paths"? How do they count that?

Unless the total CSA is greater, this can't be right. There is a little thing called skin effect that's relevant to high-frequency AC but not sparking. Meh.

The Advertising always makes them seem so much better!

I was recently looking at Ordering some 'New Spark Plugs' so I decided
to take one of them out, just to confirm what Brand and Type to Order!

They were NGK's BKR6EK twin electrode, and they quite dirty and oily...
Not at all surprised, considering that they were last changed back in 2004...

I gave that Spark Plug a good clean, put it back in and thought nothing of it!
Later that day I went for a Drive, and there was a quite a noticeable change!

Now, I really was surprised... So I when I got home, I took off the Engine Cover
and cleaned the other 2 Spark Plugs that I could get access to, as the other 3 require
the Manifold to be removed, and that's out of My Level of Skill, at this Point in time!

I'm still shocked at how something so simple, made the drive so much better!

There is a how too over on the .com website

simples mate ,

either stick with the genuine plugs not the bosch ones and as for the getting to the rear plugs i will let you know quickly as i wasnt sure how these were accessable but until my oil cooler went well lets say ive had a few times doing it:


undo the four bolts that secure the plastic v6 cover on.


undo all the following bolts as circled as well as unclipping the throttle cable from the nipple

then move the big clumbersome inlet manifold to the right of the bay and you then see how you replace the sparkies.

and make sure in the middle where the inlets to the valves are that you shove some rag or some other stuff incase dropping anything into the holes cos that would mean new engine lol

and most importantly you will need to purchase a small inlet manifold gasket
