Thread: HKS spark plugs

  1. #1

    Default HKS spark plugs

    Im thinking about doing my tune up on my evo its been about 25k since the spark plugs have been swapped, looking at nkg's but hks has a M-series plug but the cost difference is huge... Has anyone used the HKS plugs? Is it worth it? The heat range difference is huge between the two. Are there any other types of plugs I should be looking into?

    -thanks

    Do you have a 8 or a 9? If you have an 8 I would just go with the copper NGK's and change them often, they are cheap as hell and easy to get. If you have a 9, I would go with the stock NGK or Denso alternatives. No real reason to spend big bucks on spark plugs IMO.

    I mean plugs are important but dont think you need to spend too much for plugs since they got to be change every so often anyways. Stock heat range should be something you are looking for unless you are push more way HP than stock.

    Just dont get super cheapy ones. I changed once at 15k with NGK iridium ones(Stock replacement) currently using Denso iridium ones for my IX from SE when I did 30k with them.

    +1 with the last two replies, I think good sparkplugs are needed in order to have our cars running good, without any sort of hesitation ro sputtering, or even detonation. I wouldnt go all crazy spending $100 per sparkplug unless you have a fully built race car. By the way is this the one you are considering buying?

    Get NGK copper plugs BPR7ES gapped at .024-.025. They are only $2/each and our cars run better with them than the iridiums. Do a search on evolutionm.net, you'll find I am right.

    Copper is a better conductor for electricity than iridium or platinum, they just don't last as long. You have to change them at least every 5k miles.

    No need to test them. They have been used for years on our cars. In fact, my car ran smoother with them once I found the proper gap. .024-.025

    Their only flaw is that you have to change them every oil change. But at $2/each they are definitely nothing to hurt your budget, just more of an inconvenience.
