I've got a 99 ej9 1.4i (D14z2) just wondering what plugs are good to run in these the engine is stock but looking to upgrade soon

 

Use the stock conventional NGK ones. The only advantage to platinum is longer wear life, but since you're not paying for labor to replace them, the overall cost over time is about the same. Definitely do not use the gimmick ones that have more than one side electrode.

The stock ignition is quite powerful and will work with just about any non-turbo setup.

 

👍 sweet thanks, I was wondering what the perks of platinum were I've searched the advantages on the net but could only find what ngk had to say about them, and all manufacturers think there products the dog but without actually explaining why.

 

im fairly certain the stock plugs are double platinum NGK or DENSO thats why there good for 50,000 60,000 miles.

 

Yeah I'm just under 50k Miles now and the car is spotless previous owner is a Honda enthusiast and im sure he would have kept all the plugs in shape, but i might run platinum plugs just because they last longer and are support to deliver a better spark
