High-Performance NGK 4644 V-Power Spark Plug - BKR7E, 1 Pack: Ignite Your Engine for Optimal Power Review

Arrived quickly and works great! I like to use copper connectors in my MK4 Jetta GLI 1.8T. It's chipped and this area is colder than standard candles. Smooth idle and acceleration, very very satisfied.

Bought these connectors for my Lotus and they work great. I took them instead of iridium because of the lower cost and read that they have a larger and more reliable spark. I only drive this car a few thousand miles a year and I care more about performance than durability. Great offer!

I use these on my customized 1.8 ton Beetle. I try to change them at every oil change, but I've put a whopping 10,000 miles on one set. They looked a little dirty but still worked decently. (It slows down a bit when idling, but it's not noticeable under load). Great plugs at a great price. However, make sure you close them. They are too big for my taste.
