NGK Iridium Spark Plugs Reviews

I haven't noticed any difference from anything else I've used.

Great price, been using these in all my cars for years and never had a problem. Steve at Kseriesparts is the man!!!

I didn't notice my car start up any faster but my gas milage is awesome now :)

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.

Everything one can expect from a spark plug. Car runs smooth and is a good price for the set. Much thanks to ClubRSX!

These are the best priced and in my opinion overall best plugs you can get, I've been using NGK plugs for several years and they are the great

Great plugs, car runs as it should. Changed at around 80k miles, car runs great with them. Good plugs w/ no loss of power or anything. Great price as well!

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.

these are really good spark plugs and also a good price for them

changed plugs at 75000 miles. immediate difference. car idles a lot smoother than with old plugs. throttle response is better as well. great plugs for $35.00.

It took about 10 minutes to install and I noticed the difference immediately.... car runs great!!!

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.

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!

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

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.
