![Question](https://www.rx8club.com/images/icons/icon5.gif)
Got a set of Trailing and leading Spark Plugs off Mazsport this week.
http://www.mazsport.net/store/index....duct_list&c=12
When I opened the box I was like
ok this dont look right.
Last time I changed my plugs I got them from Mazda and the box's the spark plugs came in where white and had blue printing on the box's and told you where to install them on the Car.
These dont tell you where to install them on your car and the box's are yellow and have NGK in red
The tips of these spark plugs are also different from the ones I got at Mazda. These are cut with a X the spark plugs I got at Mazda had what looked like spikes facing the center of the plugs and thats what the ones I took out of the car looked like. Not like this.
These also have rings on them and have two rings on the Trailing plugs
Take a look at the pics and tell me what you think,

Well I know I can use them cus they screw right in like the OEM ones, but should I use them?
Are they a direct replacement for my OEM plugs? and will I have any problems with them?
Thanks,

The same exact thing happened to me. Mazsport's ebay site is very misleading. I had purchased two trailing "OEM" as advertised, but instead got these rx7. I emailed with a complaint, and all I got was someone saying that I don't know anything about rotaries and that they fit correctly blah blah blah.
That was not what I had complained about...
I was complaining about the false/misleading/insufficient advertising of the plugs...wow

they can be used but they are not quite there for top performance on a na car. who have to use 2 washers on the trailing plug so the tip of the plug doesnt bottom out and on the lead plugs use no washers. AND when you do that you have to retighten them from time to time as they will vibrate loose!
