    Will It Fit Your Vehicle?

    This part should fit your vehicle. It is a universal part.

    Description

    NGK iridium plugs represent the ultimate evolution of spark plug technology and performance. The iridium center electrode is both stronger and harder than platinum. This allows NGK engineers to design an ultra-fine (0.6mm)center electrode reducing the voltage requirement for spark. This allows for a brighter, stronger spark from your existing ignition system. The ground electrode has a tapered cut at the firing end which reduces quenching for better flame core growth and increased ignitability. The combination of fine wire center electrode and tapered cut ground will increase performance, improve acceleration, and fuel efficiency.

    Good Plugs

    Replaced the old plugs with these when I purchased my car. Didn't really need them, but replaced anyway. Fit perfectly and car continues to run well 3k miles later. Recommended for the price.

    NGK spark plugs

    Like always clubrsx shipping is always fast and excellent. If their a problem they call you direct and explain it to you. Didn't have a problem with this item. Basic maintenance was need at the time I bought the plug. The old plugs I had were worn. Put these in and it ran like it usually does.

    Couldn't get a better plug!

    I threw a code, went to auto zone to check it out. Apparently I had a misfire in the #2 and #4 cylinders. The BOSCH plugs that I was using: one fouled out and the other looked like it was going to fall apart in my hand. Replaced all four with the NGK iridums and I couldn't have gotten a better plug, period. Better acceleration, a little bit less of a lazy tach, and of course no codes! Everyone should get these or atleast some version of them.

    Great spark plugs!

    I replaced them at 70k miles, I'm pretty sure I still had the originals in there because they were completely shot. Instantly gave me an extra 2-3 mpg for each tank...so they'll pay for themselves after a few tanks of gas. Well worth the money!

    worked great on my 05-S with 45k

    even though my car is less than half of the recomended tune up time, these plugs a solid difference in performance.

    Awesome spark plugs

    Bought 2 sets of these now from clubrsx. 1 set for my turbo setup and another set for my recent NA setup. These are GREAT spark plugs, I would everyone to buy these.
