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!

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.

Check your order first
I have no problem at all about the product, my car run smoothly but I do have a problem about the handling. I advise anyone that ordered multiple item , please check your order and make sure you receive the materials that you ordered. I ordered 4 spark plugs and one of it is not the same serial number. I had to ordered it again and luckily I received the right one this time. The shipping is fast , I recommend this product but check it first.

Works fantastic in my turbo engine
Bought these for my 1.8T VW Jetta and so far am very pleased. Most platinum plugs have hair thin electrodes that just don't work well in turbocharged engines. The high boost pressures require a fatter spark and so I've been running NGK copper plugs because the thick electrode provides a noticeable boost in performance. The problem with copper is it just doesn't have the longevity of platinum, requiring frequent changes. This plug provides that fatter spark, and being platinum will hopefully prove to be long lasting. Can't beat the price either.

Perfect replacement
Worked great in my 2000 Toyota Tundra, no issues, shipped quickly. Not hard to replace, although the deep channel caused a temporary panic when the spark plug socket came off the ratchet extension. Used the spark plug socket to start the plug after lightly engaging the plug into the rubber collar of the socket, then removed the rubber collar from the socket to tighten. Could have used a deep socket instead I suppose.

Excellent plugs!
Bought this for my last car because I was experiencing some stutter when I accelerated, and the only thing that seemed to keep coming up was spark plugs when I searched for a cause online. Well, indeed that was the cause! I had purchased some cheap (sub $2 each) plugs from a big national auto parts chain, and a known brand, but they did not work in my Honda! Well, they worked, but not near as well as these Denso's when I swapped them out! The stutter completely disappeared, and it made it easier for me to sell the car when I recently upgraded. So, don't cheap out, if you have a Honda, get these (and, they really weren't that expensive from here).
