NGK BKR7EIX IX Iridium Plug

These are genuine. Not like the ones they sell on ebay that claim to be genuine. Those aren't

Always quality w/real NGK (made in Japan not made in China NGK). One step colder plugs for my turbo wrx. Noticed immediate improved starts, smoother idle, holds boost to redline. Had an issue where I’d hit 75% throttle and fall flat on her face. These took care of it. Repeat buyer will return when it’s time. Top-notch seller and fast shipping arrived a day early.

Works just like original OEM, will purchase again when needed.

so far performance is ok!

Bought these for an Audi B6 A4 with APR stage 1+. No vendor lists them as compatible for my vehicle but I compared the specs on NGK's website and everything looked the same as the BKR7E's I have been running. Being tuned allows for one to typically gap smaller (.28-.32) as well as run a cooler plug; and running R8 coil packs which burn a lot hotter and provide a stronger spark one could open that gap back up (.32-.40mm I hear for the 1.8T application)I have been using the copper plugs previously and although I was enjoying the perceived change from the butt dyno test, I felt like the car has been cold starting a little hard during this quattro season. Also the idle wasn't as smooth as I'd like and I assumed that it might be to the gap change taking place with the Cu plugs. I was getting tired of going out in the cold, wet, winter weather just to pull them and re gap after a few thousand miles so after doing some research on the different types of plugs it appeared that Iridium would be the best combination of the Cu plugs' performance and the Pt plugs' longevity. time will tell if this is true.

These came pre-gapped at 0.025 (all 4 spark plugs) instead of 0.032 as mentioned on the item. So, I had to regap mine which added a good 10-15 minutes to the entire process of replacing the spark plugs on my MK6 GTI. I bought these to go with the R8 coils that I got to replace the factory coils. They’re working great, just didn’t like being inconvenienced for having to regap them.Update: I decided to purchase another set and replace the old ones after 20k miles. They still came at 0.025 gap, regapped them to 0.028 as I am now running IE stage 2 tune. The old set still looked great after 20k miles, I'll keep them for emergency use.

These are premium spark plugs and definitely authentic NGK iridium IX, you can tell straight away from the packaging. If you have any hesitations because of price, don’t! I could tell a noticeable difference between these and auto lite I had before on ignition and acceleration! Nothing huge but a definite difference! We’ll see if they hold up though!

Best workhorse performance/daily plugz out there! Worth every penny. Also was fast and easy to order from this to receive my new set. Which are installed and ready for the cold weather season to start. Highly suggest others to prep their vehicles with a few low cost items like these to ensure dependability. Will always have these Iridium greatnesses in some form as a standard to any vehivle I own or drive.
