NGK IFR7G-11KS Laser Iridium Spark Plugs 4 Pack Reviews

Had NGK’s in my other Civic. So when I bought my 8th gen si, I had to have them.

My ‘09 Civic Si was in desperate need of new spark plugs, after putting these new ones in my car immediately ran 10x better. Highly recommend

I'm extremely happy with the purchase. These plugs brought my car back to life. Really can feel a noticable difference in throttle response, smoother idle, and just overall driveability. I highly recommend these to any k series owner.

The car feels alot different

Best 50$ I ever spent , very easy to install. Only took 5 mins to install.

Great plugs, best for the money. Fast shipping from Kseries, too!

Got my rsx with some BS auto lite plugs in them, swapped them out and the car woke up!

Great product!! after taking out my old spark plugs and switching them I felt a pretty big difference.

Car starts up and runs much smoother now. Had just under 60k on my old plugs and wish i would of replaced them sooner.

Great spark plugs, got my order on time can't complain!

It takes a set of fresh plugs to get back lost performance and fuel mileage.NGK is the way to go.

it's a simple fix and should be on your to-do-list!

I ordered these because it had been about 80k miles and when the shop switched them out during an oil change the advised that my old ones showed that I was running lean. These plugs are great though. Good gas milage with new plugs.

Good stuff

Great investment Fast shipping worth every penny.

Great sparkplugs, I have always used NGK even in my previously owned car. Worth the cash.

Awesome!!! feels great!! and shipped fast!

Just did the change last night. This was the easiest and most straightforward maintenance change i've ever done. These are exactly the same ones that I pulled out from my car. Don't know if its OEM.. or maybe the previous owner already changed to these sparks, but the old ones were pretty dirty and looked worn out. I can't comment on noticing any difference, cause i don't have measurements, but we'll see if my fuel economy improves. The car seems to start better. but again this could just be a placebo.

They do what they're supposed to do. For those that are saying it gives more power, it's a placebo. You do not need a torque wrench, it says right on the box 1/2-2/3 turn after it fully seats. Use anti-seize on the threads.

No complaints.

Great price. Fast shipping. Thanks Club RSX

I ordered these for my 100k service and is working well with the K20. I'm not boosted, so there was no reason to mess with the factory specs on spark plugs. Be sure to torque each plug down to 18 ft/lbs when installing the new plugs...

Got these when I threw on alot of bolt-ons and i've got to say it woke the motor up. Can't say I feel a huge power gain out of the deal but you do notice improved throttle response which is always a plus. This is a good product.

This was my first sparkplug change in my car only to realize that I didn't even really need to change them, but I changed them anyways. But I really gotta say you can feel a small kick out of the whole deal. Runs a lot smoother as well. Best spark plugs I've seen for my Civic SI.

Very happy with my purchase. Great plugs

I was skeptical at "feeling the power" of the spark plugs but I actually did. My old ones were slightly mis-firing and these are just perfect. Smartest $50 I spent on my build so far!

really good sparks plugs and great price on CRSX!!!

great set of spark plugs... felt the difference... best bang for your buck

great perfect replacement

These are some good spark plugs. I picked up a few MPG since my old ones had a lot of miles on them. I also think they added about 40whp, but I could be wrong. CRSX had quick shipping and a great price.

when it comes to spark plugs, NGk is one of my top choices, excellent price on ClubRSX as well!

I bought these plugs cause they are OE replacements and they worked great of course. Fast shipping and took like 10mins to put in. will definately buy these again next time i need some.

Replaced these at 105,000 other ones looked pretty worn. Brand new and fast shipping. ClubRSX is great, thanks.

i put 140k on my stock plugs w/ no problems. replaced them when i realized they were 100k plugs. honda wanted over 100. put them in, work great.

I have 50k on my clock, so i decided to pull the plugs and do a replace, since i'm sure they were oem. Ordered them online because it was a lot cheaper than in the store. Haven't really noticed a HUGE difference, but i'm sure the reason behind doing it when i did it was preventative maintenance. CRSX has fast, reliable shipping.

These plugs are OEM spec plugs that are a great replacement and maintenance item for your RSX. The price on ClubRSX is unbeatable too. The dealership will charge you $25 per plug and Honda doesn't even carry these; your only option is through Acura. Great plugs, great price, and peace of mind.

My car was misfiring for quite some time now. So I decided to replace the plugs. Since then, no misfire. The plugs are great quality, and Cub Rsx's price is very competitive.

The dealer wanted $120 at 60K miles to merely clean the old ones and put 'em back in. Instead, for about $50 and 30 minutes of work, I just replaced them. Plugs don't need to be gapped and you're good for 60-110K miles, depending on if you clean them or replace them.

These spark plugs are great, car really felt new again. The manual says to replace them every 100k miles, but in reality, you should replace them much sooner. Trust me, buy them and try them for yourself.
