    No more NGK spark plugs? I was told they are designed differently now.

    I went to get the NGK spark plugs today from advance auto. When I got home, instead of having threads on one end, it was a metal cap (non removable). Took them back and the advance auto guy said they changed their design. Same model number though. Anyone else run into this?

    Which part # plug did they give you ? Should be the NGK DCPR8E 4339.

    I have ran into the problem of receiving the non removable cap before.

    O'Reilly Auto Parts usually has them in stock at a good price.

    You got the wrong spark plugs. These are the plugs you need

    There are two different kinds and the dude does NOT know what he is talking about. I have a whole box right here of them. One has screw off caps and one does not Hence the 4339 designation.

    +1.... just ask for them by the stock number, not plug number.

    Yep, the stock number is the best way to ask for them. I've had that same issue in the past with my 2-stroke quad and dirt bike plugs, BR8ES.

    Here's a tip for you, when you buy them, buy a case of 10 so you always have extra. I also keep 3 in the ski, you never know when or where you'll need to change them.

    Ask me how I know....

    Same shit happened to me.
    Is there any benefit to having the solid core? Just wondering wtf the reason is for having 2 different styles of the same plug. Maybe the true solid core has less resistance than the screw on cap, or maybe because the caps can come loose? Hmmmmm.
