Just stick some bp6es's in dude, no need to go fancy. Ngk are good plugs.

[bmcecosse]

Champion N6Ys (now known as RN6YC) will be ideal - had all sorts of problems with NGKs - I'll never use them again. If driving the car hard you may want to consider C57YC racing plugs

What sort of problems were you having?

[Wil_h]

The onlt thing that can be better about a spark bug is reliability and service life. I find NGK to be more than up to the job. No point spending loads on more exotic plugs claiming better conductivity as a modern resistor plug has a fixed resistance, so you're just chucking money away.

And whatever bloke down the pub says, spark plugs will not inprove the performance of your engine. Any test that shows they do is flawed, most likely using knackered plugs to start with.

Do you want a lesson in Spark plug technology ?

Yeah, why not. But remember the above is simplified to discourage people from spending money on plugs unnecessarily.

totally agreed no need for fancy spark plugs for a road car.

Before I get into the advantages of using different design and materials for spark plugs, even for a road car, don't you want free HP from a simple change of spark plugs ?

I'm not sure what you are asking. Are you saying that HP can be got from changing a spark plug? I mean real HP that would be worth while and measurable not only on a dyno by by your right foot.

The only other advantage I can see a 'better' spark plug achieving is longevity and reliability.

That's exactly what I am saying.

[Wil_h]

Then I need some evidence. I would say to be measurable with your foot you need 5% increase in power.

So we're looking for evidence of a comparison between two sets of spark plugs, one 'standard' brand new set of the correct rating, compared to a second set of 'improved' new plugs.

Below is just one example I can find.



Please note that only NEW plugs were used for testing on the following tests.

This first test vehicle was a 1991 Nissan 240sx, we tested 4 types of plugs total 3 of which consisted of Brisk models. The only modifications this car had from stock form were a cold air intake, dual electric fans, cat back exhaust system and a 4-2-1 header. Approximately 20 mins were given between each test run to ensure accurate results.

The Following Plugs were tested in this 240SX:
1) NGK Copper Plugs, 89 Octane Fuel, MAX POWER = 139.8 / MAX TORQUE = 143.8
2) Brisk DOR14LGS, 89 Octane Fuel, MAX POWER = 141.3 / MAX TORQUE = 146.6
3) Brisk DOR14ZC, 89 Octane Fuel, MAX POWER = 141.6 / MAX TORQUE = 148.7
4) Brisk DR14S Silver, 89 Octane Fuel, MAX POWER = 143.3 / MAX TORQUE = 150.1

The final result was a MAX POWER gain of 3.5whp and MAX TORQUE gain of 6.3ft/lbs.
This gain was achieved by using Brisk DR14S Sliver Plugs.

The second test vehicle was a 1992 Honda Civic Hatchback, we tested 2 types of plugs 1 of which consisted of a Brisk model. Modifications this car had from stock form are too many to list, basicly it had a fully built turbocharged Type-R motor, running 15lbs. of boost on 93 Octane pump gas. Approximately 20 mins were given between each test run to ensure accurate results.

The Following Plugs were tested in this Honda Civic:
1) NGK Copper Plugs #8, 93 Octane Fuel, MAX POWER = 312.6 / MAX TORQUE = 241.3
2) Brisk DOR14LGS-T, 93 Octane Fuel, MAX POWER = 336.7 / MAX TORQUE = 254.1
The final result was a MAX POWER gain of 24.1whp and MAX TORQUE gain of 12.8ft/lbs.
This gain was achieved by using Brisk DOR14LGS-T Plugs.

The third test vehicle was a 1998 240sx, we tested 2 types of plugs 1 of which consisted of Brisk a model. This 240SX has an RB25DET Skyline motor, fine tuned with an Apex-i SAFC, running 12lbs. of boost on 93 Octane pump gas. Approximately 20 mins were given between each test run to ensure accurate results.

The Following Plugs were tested in this 240SX:
1) NGK Copper Plugs, 93 Octane Fuel, MAX POWER = 263.2 / MAX TORQUE = 229.0
2) Brisk DOR14LGS-T, 93 Octane Fuel, MAX POWER = 268.0 / MAX TORQUE = 234.3
The final result was a MAX POWER gain of 4.8whp and MAX TORQUE gain of 5.3ft/lbs.
This gain was achieved by using Brisk DOR14LGS-T Plugs.

The first 2 pulls viewed below were made to correct air/fuel, once this was achived the final pull (DYNORUN.003) was our baseline for the NGK plugs.

The fourth test vehicle was a 2004 Mach1 Mustang, we tested 2 types of plugs 1 of which consisted of Brisk a model. This Mach1 Mustang was completely stock on 93 Octane pump gas. Approximately 20 mins were given between each test run to ensure accurate results.

The Following Plugs were tested in this Mach1 Mustang:
1) NGK Stock Plugs, 93 Octane Fuel, MAX POWER = 270.3 / MAX TORQUE = 290.2
2) Brisk GOR17LGS, 93 Octane Fuel, MAX POWER = 275.8 / MAX TORQUE = 300.8
The final result was a MAX POWER gain of 5.5whp and MAX TORQUE gain of 10.6ft/lbs.
This gain was achieved by using Brisk GOR17LGS Plugs.

In conclusion every Brisk plug that we tested gained a minimum of 3.5whp and 5.3ft/lb of torque and in some cases gained up to a 24.1whp and 12.8ft/lb of torque. We were very satisfied with the results that we achieved and definitely recommend these plugs to individuals wanting to make the most power from their engines.

I would like to give a special thanks to the guys at UTI, Universal Technical Institute for allowing us to utilize their dyno for testing purposes.

[chipster196]

ive had race ad road minis for the last 10 years. I run NGK BP6ES and their fine, my ce has a stage 1 mg metro engine and i change the plugs every year and not once had a problem with them, usally they come pre gapped but i check the gap anyway then fit then and dont touch them till a year later

[Wil_h]

So a couple of % in all cases other than the honda, I would rule the honda out of the equation as the NGKs were most likely unsuited.

What I would have liked to have seen is the first test repeated at the end after a 20 minute rest as the first test was not the same as the rest. Although a set of 4 plugs will set you back at least £60.

Generally I think that if you spent 60 notes on these there would be little benefit if any on an A-series making maybe 80bhp.

My conclusion, more convincing required

Well that was just 1 example, and there are many many more like it, do a little research yourself and you may be quite surprised!

And the benefit gained from a simple change of plug shouldn't be dismissed so lightly, we all want as much power as we can possibly get, so why not have what is essentially free HP from the simple humble spark plug!

So on an A series producing 80hp do you really want to say NO I don't want an extra 4hp because I have enough thank you!

When I changed my spark plugs to the mentioned BRISK spark plugs, I got a definite benefit, and now won't use anything else, in my cars.

[Wil_h]

Only 1 car in that test made more than 5% increase, the rest were more like 2%, which on an 80bhp engine is 1.5 bhp, at £60 for a set it's hardly free bhp, also none of the tests were using a carb'd 5-port.

After a bit of research I have found reviews good and bad, certinally not weighted in the good. If you feeel it's good value then fine, but I'm not prepared to risk my cash.

If the gains were really real all cars would come out of the factory with them, if manufactures could find 5% (or more) increase in power for what is a small cost compared to developing an engine I'm sure they would.

Where did you get your price of £60 from ?

The most I've paid was £48 for the mentioned BRISK spark plugs!

And the reason such items are not installed at the factory are, the manufacturer wants to provide longevity as apposed to performance, that's why most spark plugs in new vehicles tend to be either Platinum or Iridium, these offer the longest service life, but not performance.
