Standard or turbo plug?
I'm not really sure of the difference between a standard and a turbo plug engine. Would anyone be kind enough to fill me in on the differences, pros/cons, or preferences? Thanks.

A turbo plug has a tapered base which seals into the head, removing the need for the copper washer.
Turbo plugs are said to work 10-15% better than standard plugs.

Guideline 1: Know what type of engine you have. Is it a standard - or a turbo?
Standard engines (engines with a 1-piece head) are most common. Standard plugs are easily available, inexpensive and fit almost all standard engines. Standard plugs are installed with a washer, which creates a compression seal with the head.
Many new O.S. engines are turbo engines, which feature a special 2-piece turbo head. The biggest benefit of turbo plugs is superior performance. Unlike standard plugs, turbo plugs (identified by a "P" in the description) feature a tapered "seat" that matches perfectly with the head. That creates a superior compression seal and with it, maximum efficiency and power. Turbo plugs are the choice for racers who want - and need - top performance.
A word of caution: you should never install a turbo plug in a standard engine or vice versa. Doing so risks doing serious (and expensive!) damage.

The o'donnel plug is great to use as a turbo plug. They are $5.50. I always use the 1/10th scale one in OS motors they work great.

The OS turbo plugs are great but are for OS&Ninja engines. P3 has to be one of the best plugs out there for shorter tracks and P4 for larger.

Yes I just checked it the 77t. They lasted me as long as the p3's I used before that. Both my v-spec and speed ran a little better with the O'donnell plug. Can't say that it will be better for all engines but that is what I like to use. And the price just went down by a buck so $4.50 is at standard plug prices. I can't say anything about the p4 plug however I have never used it.

Turbo plugs generally last longer than standards as long as its tuned right
