🔥 NGK 4291 V-Power Spark Plug - ZFR6F-11, 4 Pack: Top-Quality Ignition Upgrade for Optimal Engine Performance Review

I bought these for my '99 Honda CR-V and now the car drives much better than when I bought it and has done over 200,000 miles. Really good spark plugs!

Ordered these for my 2001 Ram 1500. When I checked they were already 0.40 apart and I didn't need to adjust them. And my truck works great. Not knowing the history, I pulled out old champs that were badly worn, I wouldn't put champs in my lawnmower. this is a good buy

I have a 2004 Honda Civic ex. I ordered these spark plugs last year and was too lazy to put them in. I eventually installed them and as soon as I left my mechanic's shop I felt my car was much stronger and smoother. Acceleration was smooth, without jerks. Definitely the choice of candles!

I bought these spark plugs when a friend suggested I change the spark plugs in my 2004 Honda Civic. I'm not sure if this solved the problem, but sometimes I would feel my engine getting harsh at idle, especially when pulling off an open road and waiting at a red light on a slight incline. Since I changed the spark plugs I no longer have a hard idle feeling.

Fits direct to a 2002 1.7 liter Civic. Eliminated misfires, easy replacement, took about 30 minutes to change spark plugs and coils. It would have taken less time if one of the old spools hadn't fallen apart while being pulled. Starting work on these engines can be done by anyone to save on the monster mechanic's bill. Literally nothing unless you know how to use a ratchet/socket. $57 for replacement spark plugs and coils. You might as well do both if you want to do one.

I have used them on a 2002 Honda Civic LX (1.7L I-4) with great results. The owner of the car did not drive many kilometers on it, so there was no need to buy iridium tips three times more expensive. Although they don't last 100,000 miles, they are actually the equivalent copper core connectors. This means they have the same thread size and heat range. The NGK website has an excellent spark plug decoder to understand the nomenclature of their names. In the short term, you won't notice any…

I bought 4 of these for my 2004 MazdaSpeed Miata (Mx-5). They fit perfectly. There are several enthusiast websites/forums that recommend using them in turbocharged cars due to the deeper seat - they are located deeper in the engine where the spark can be more effective, especially compared to regular length spark plugs. I'm not 100% sure what the science is behind this, nor am I sure how they compare to iridium, platinum, etc. I pulled my old spark plugs when I did a 60k service and they looked

Installed on 2004 WJ Jeep Grand Cherokee No HO 4.7L. Direct replacement for factory Mopar SPRC12MCC4 and Champion #439 forks. The gap in this application is 0.040 inch. Plenty of cars that recommend a copper connector are good for upgrading to platinum, iridium, ruthenium or any other new magic metal and crazy connector design claiming massive performance increases and +3. -5 mpg. For some reason the 4.7 gets angry and causes pre-ignition at certain engine temperatures and RPM with unicorn dust
