V-GROOVE FOR THE SAME PRICE AS STANDARD PLUGS!

So what's in it for me?

Simple...happy customers, who'll probably be thanking you for improved vehicle performance, and for helping them save money at the petrol bowser!

V-Groove plugs can provide some of these benefits:

Reduced voltage requirement
Improved starting
Improved fuel consumption
Cleaner exhaust emissions
Better acceleration
More stable idling

How is all that achieved?

The v-shaped groove in the centre electrode and a slight concavity in the ground electrode lead to the spark being concentrated at the edge of the electrodes, thus reducing the amount of energy absorbed (known as the quenching effect). This means that more of the spark's energy is available to ignite the air/fuel mixture.

Yes, but what does it really mean?

Engine manufacturers are always striving to run on leaner mixtures to improve fuel economy and reduce exhaust emissions. Therefore, with more of the spark's energy available to ignite the mixture, it is possible to run a leaner mixture with V-Groove compared to standard spark plugs.

See the graph below.

How do I know that this is not just theory?

We've had our V-Groove spark plugs tested by a leading university to the Australian standard 2877, and then compared the results to those of standard spark plugs. The tests were conducted using a Mitsubishi Magna 2.6 litre engine and a Ford Falcon 3.9 litre engine, for both highway and city cycles. The results showed reductions in fuel consumption of between 2.7% and 3.6%.

If they're so good, why don't all the car manufacturers use V-Groove?

Many do! Our design is patented, so only those manufacturers who source plugs directly from NGK can use V-Groove. However, NGK is the largest supplier of original equipment spark plugs in the world. Many of the brands we see in Australia use NGK, including GMH, Toyota, Nissan, Mazda, Honda, Mitsubishi, Suburu, Suzuki and Daihatsu.

What types of plugs are available?

The following conversion table lists popular NGK part numbers and the V-Groove equivalent.

Can I use V-Groove spark plugs where, say, a BCPR6ES was specified as original equipment?

Yes! The conversion table above lists exact equivalents. All physical characteristics are identical. So you'll find thread reach, thread diameter, heat range, etc, are exactly the same. It's our V-Groove that makes the difference.

How about the some of the later models?

As you're probably aware, many of the newer models in Australia already use V-Groove spark plugs. To name just a few: BKR6E, BKR5EY, ZF66F and BKR6EF are all V-Groove spark plugs.

You may have noticed, that in general, where the "S" has been deleted from the NGK part number, that the plug is V-Groove. Another quick way to recognise NGK V-Groove plugs is the green printing on the packaging, and also the green part number on the plug's ceramic insulator.

Where can I get them?

V-Groove spark plugs are available from all the normal NGK stockists, for the same price as standard plugs.

Go for V-Groove and you're likely to improve customer satisfaction at no extra cost or effort!
