  • Simply Awesome Spark Plugs
Simply Awesome Spark Plugs. I wish i knew about these when i had my previous Honda Civic. Installed these in my 2009 Honda CR-V (Replaced NGK ZFR6K) and from the get go i have seen exceptional improvement in acceleration smoothness, power and in MPG. I can say there seems to be something behind them being double platinum tipped and not just hype. The price in these are great (less than the standard plugs i took out) and being platinum should last a longer time. Iridium's to me were just too expensive to substantiate me buying them. I do not believe any standard spark plug should be in a vehicle for more than 2 years. As i have seen many coil packs fail due to worn out spark plugs. With these being Platinum i may keep them in a little longer say 3 years or so before taking them out for inspection to see if they can go longer. ... show more

  • These are Made in Japan
After adjusting the gap, they work great. Engine idle is smoother and acceleration feels more responsive. Gas mileage is about the same. I bought them for a Honda Civic LX 2004.

Good quality. I put these in my girls 2002 4.7 Toyota sequoia and she spun tires (whoopsy) on the first test drive. Don't forget to always set you gap on new plugs folks.

  • Surprising results in a Porsche
I bought a set of these plugs for my 2002 Porsche Boxster. The Boxster had 50K miles with the OEM plugs, made by Beru, a French company. Those plugs have four prongs facing towards a fat center electrode. The Boxster uses a coil-on-plug design, and those Beru plugs were noticeably worn with a big gap between the electrode and prongs. I've always been a fan of Denso plugs, but have tended towards their iridium plugs. Their iridium plugs have invariably increased my observed mpg consistently by at least 1 mpg. With the Boxster, though, I wanted to try something different, so I got these plugs. I was surprised at the difference in performance that these plugs made. I felt a big increase in bottom end torque and the engine winds up to redline without a worry. For the price, they are a flat out bargain. I like these plugs, and my Porsche really likes them, too! ... show more
