Final thoughts

You might be thinking will these products fit my car? This is a valid question. Not every spark plug fits every car. There are different kinds of spark plug for different kinds of cars. But the information might surprise you that none of the car manufacturers make their own spark plug. They mainly outsource it.

If you have Toyota car you can check the spark plug right now. I can guaranty you that you will find a Denso plug. So it kind of gives you guaranty of the same quality of product that is given by the manufactures. If you still are confused you can get help from the owner manual.

But some posh and sports car needs a special spark plug. Like BMW’s cars have their own prototype spark plug. These only can be fit in BMW’s engine. Expect these most of the vehicles will fit these plugs. These are the best product for the car. Normally you have to change the plug after every 90 KMs.

Hope this will help you choose the right product for your vehicles.
