I am amazed at how well made the product is, just magical!

Previously, there were already iridium candles and worked for me for a very long time. So I decided to fork out and buy them again. The choice fell on these candles. Many write that one candle comes, instead of four. So you need to order right! The price is indicated for one candle and when ordering, you should have 4 items in the basket in the amount of 4700, only then will the complete set come. As for the work, beyond praise! The engine runs smoothly, as far as it is generally possible for a

Pros
  • Excellent quality, compatible with various cars, long-term use.
Cons
  • No.

So much for customer service

I bought a set of premium spark plugs for my VW Vanagon as recommended on their website. When I went to install them I couldn't remove the ends of the electrodes as is required for installation on any old VW. I tried to contact Denso through their website and hadn't heard back for two weeks. I don't think spending $29 on a set of 4 forks is enough to get an answer. There was no phone number on the contact page but I finally found the phone number for the Ohio plant that I will call on Monday.

Pros
  • Denso # 4709
