NGK Spark Plugs BKR6EIX-11 Spark Plug

Be careful with the plug selector on this page for these plugs. For my '97 Mazda Miata, it recommended the BKR6EIX-11, which is correct for earlier 1.6L Miatas ('90-'93), but incorrect for later 1.8L cars, '94-'97, which should be the BKR5EIX-11. Luckily, I had an old set of plugs from a year ago, and noticed the different number before I installed the 6EIX plugs I'd ordered. When I double-checked by using the NGK plug-finder on the NGK.com site, it confirmed the 5EIX was the correct plug for the 1.8 cars. (There's a reverse system on the NGK site, just insert a plug number and it'll give you a list of all the appropriate cars for that particular plug.)Amazon was great in taking care of a super quick return. The only problem was that I couldn't do a straight exchange, it had to be a separate return and new order. I'm a prime member, and they did offer a free upgrade to one-day instead of two-day shipping for the new plugs, proving once again that Amazon is really great on customer service!

Great product

This item is fantastic! I have been searching everywhere for these spark plugs and not only did I find it for the lowest price, but I ordered the item late in the afternoon and it arrived the very next morning from 3 states over. So excited! I cannot wait to put these babies in my car! Very satisfied customer! I've used these before and they are amazing. Just figured it was time for a replacement. They truly last a long time. Bought my 1994 3000GT 6 or 7 years ago with 43K miles and it just rolled over to 98K and still runs like a champ with these plugs!

I just Installed these Spark Plugs in my 03 Toyoto Highlander V6, If your not a good mechanic with a good set of tool's I would not attempt this project. The front 3 are easy, the rear 3 is really hard to a access. However if you remove some of the interference such as the speed control cable, PVC valve and hose it can be done. I have 95000 miles on my highlander, the new plugs made the engine purr like new.

Although the description says they are gapped at .044 (1.11mm), mine measured at .040 (1.01mm). I decided to leave them at that because I'm not sure how accurate my measuring device is.If there are no problems, I will most likely not come back and update this review, so I'm tossing up 5 stars in a hope that everything works fine.

The listing stated pack of 4, I got 1 spark plug, complained to Amazon they reshipped and guess what I got 1 more plug. I had to insist they live up to what was listed and got 2 more. Packaging was even worse 1st arrived intact all others came loose from the boxes and rattled around in the shipping box or envelope (no consistency to how shipped). I believe the plugs survived and at some time this summer I'll install them. I thought $7 shipped was too good to be true for 4 of these and it was not worth the trouble in the end, glad I was in no hurry.

I bought a used Scion that had another brand of spark plug in it and it was running poorly. I ordered a set of these and now it is running great! It's got more power and the fuel mileage is back to spec level. This is the third car I've put these plugs in and I won't use anything different in my cars. They have always performed well. The only plug for a Toyota engine.

I've owned a decent number of Toyota, Honda and Subaru cars and have only used NGK plugs for the last 20 years (ugh, that means I'm old). Yes they work, but what always impresses me is how good they still look when I change them out at the manufacturer's recommended interval. In older models or high-mileage cars I do think you can notice the difference between these other brands, which completely could be confirmation bias but in the end I'm more than happy with NGK.
