1989 VW Polo 1.0 Engine: Comparing Bosch vs NGK Spark Plugs for Optimal Performance

I have a question: What kind of spark plugs is better for the 1989 VW Polo, 1.0 engine: BOSH or NGK? I park under a cloud. Thank you for your help!

and what have you ridden so far and was everything ok? if so, it is best to stay with this brand.

Only NGK, give Bosch to yourself, it's a scrap, not candles.

even the Volkswagen manufacturer puts NGK and the reason is Bosch is hay and they get faulty!

maybe otherwise NGK are much better than BOSCH I only install Bosch, because I have to, but so far none of the customers have complained for themselves, I will certainly arrange NGK when replacing them with those you will go and those

ps but don't put on a spark

I also recommend Champion and only company candles for Fords Motocraft.

I had NGK in my car and I will say they are good lights, no smoking problems and in general.
Why don't you recommend sparks?

because after 15,000 km they look like NGK after 40,000 and they suck at all, perfect for Fiat 126p, 125p and Polonaise

In my toddler, I traveled 70,000 on sparks. km and up to 100 thous. km they would probably work, because there were no problems with them.

well, I have a cc700 on LPG and ISKRE screwed on. So what do you advise? earlier, I had NGK and performance, combustion, firing was the same. I did not notice the difference

Sparks are good for a mosquito, Bosch if you get good art, there is nothing to complain about, NGK are very good, I also say BRISK

I heard that there are bad Bosch but I use Bosch four-electrode electrodes (previously three-electrode ones) and I have LPG and they work great - no problems due to candles.

yes, i also bet on three and four electrode bosches.

ordinary ngk or spark never bosch

I use ngk, bosch, beru, I was disappointed with sparks (very much).

There is nothing to complain about Bosch, I only use such, so much good to choose from the catalog, I and my customers have never been disappointed, NGK has already transported me, the price also

How many drivers, so many opinions. I have ridden over 500,000 km on high-speed performance motorbikes and on cars about 300,000 km, I have always used carefully selected Bosch Platinum candles and was very pleased with the 0% failure in the toughest conditions. Nemo

And here is probably the dog buried, the wrong spark plug for a given engine, even if it is praised NGK will wear out quickly (either it will be covered by carbon deposits if it is too cold, or the electrodes and the insulator cone will burn out if it is too hot).

After so many years, I will decide to refresh the topic Bosch or NGK a bit, I am just after replacing the candles in OPLU. I was surprised that a friend of the seller recommended NGK to me, I thought that this brand had become "Chinese" a long time ago, and it turns out after a long conversation with the seller (or friends who sell it) that NGK is the best brand of candles at the moment because they are not forged yet . Of course, and this time I was not disappointed at NGK.
I was strongly discouraged from using original candles for Opel and Bosch.
NGK only!

Do not make a fuss, everything will be better than Bosch and I do not even mention NGK because it is total crap. Even briskets run better

I personally use NGK. I put them on up to 8 motorcycles that I used to drive long distances around Europe.
The condition is that the spark plug is correctly selected for the given motorcycle / car model.
It is not allowed to install candles as long as the thread and length match.
Warmth is important, as someone mentioned earlier.
I must add that in SUZUKI motorcycles, candles should be changed, as the service says, every 12000 km, and sometimes one of the candles ended after driving 11500 km. We always replace all candles together, i.e. 4 cylinders 4 candles, 8 cylinders 8 candles. The exception is, for example, Alfa Romeo where 2 candles per cylinder, but not all models.
Using NGK nickel (cost of 4 candles about 100-140 PLN) for, for example, GOLF 6 1.4 80KM, after driving 30,000 km the car did not always burn the first time, after starting it often gently jerked the engine. Replacing the candles with new ones solved this problem.
We replace nickel candles max 30,000 km, iridium candles 60,000 km, platinum candles every 100,000 km, I have never used them personally.

I don't think you can judge candles worse. After all, their appearance depends almost exclusively on the accuracy of their matching to the operating conditions of the engine. If you choose their parameters wrongly to the working conditions each the candle will look like scrap metal.

God forbid I do not want to say that NGK candles are bad, but for 25 years I have been using ONLY Bosch candles and only multi-electrode ones. Of course, some are better, some are worse, but I have NEVER come across a wrong (faulty) Bosch spark, I have traveled thousands of kilometers and have encountered a few failures but, never spark plug failures. There is only one recipe: THE CANDLES SHOULD BE CARED AS ANY OTHER IMPORTANT COMPONENT OF THE ENGINE. If you pour the wrong oil into the engine, don't be surprised that you can even destroy the engine. It is the same with candles. Most often, "experts" put in "fashionable" candles, often without any idea about their parameters and purpose, and then complain that something is working wrong.
