how ever if its an 05-04 its just a cr8 plug

Ok, to clear this up I went to NGK ´s site and this is the spec for a CR8E:

C = 10mm thread and 16mm hex grip

R = Resistor

8 = heat range

E = thread reach 19mm

There you have it.

A 5/8 socket works, but is not what it´s made for. But maybe it gets the job done. 0.625 inch = 15.875 millimeter

That's funny. My NGK catalog says it's:

10mm thread

3/4" reach

5/8" hex

I guess if you're here in the states you would use a 5/8" socket. Countries in the metric system would use a 16mm socket.

I don´t get it why you mix between inches and mm´s. You should switch to the metric system and skip the fractions:lol:

The reach and hex can be measured in inches, but the thread is metric, so it just gets confused, hehe.

We're Americans and feel the need to be a little bit different.:busted: All of my measuring tools (calipers, micrometers, dial indicators) measure in inches.

Haha. I use only metric. Except for a sparkplug wrench.

I love metric when dealing on small scale. How ever when dealing with speed distance and height inches feet and miles is better.

Same thing with temprature farenheight kicks celsious ass

how ever if celcious was not based on water it would be fine.

Ohh and British thermo Units rock also. Haha

Haha, what´s wrong with basing it on water´s properties?

That is a real and useful thing.

What is 0 degrees Fahrenheit based on?

Because water is not a good base line IMHO

You didn´t answer my Q?

Edit; haha, I read up on it on Wiki, and I still don´t get it. Now I know why you didn´t answer, there is no possible way of really knowing. Haha, you just use it. haha

I do belive it's based on mercury and the height it rises.

My main complaint with celcious is actuly just does have enough space. 100 points is to small when comparing a vast amount of space between freezing and boiling. Maybe if it was 0 to 1000 or killecious would be a more apt mesurement then 100 but a

wiki said it was based upon the coldest thing that could be artificially made at the time, 0 degrees F. And then the human bodys core temp.

Only problem they couldn´t measure the core temp exactly, and were off by 2.5 degrees. Haha...

And for the record, Celsius doesn´t stop at 100 degrees. Haha, it has no upper limit because it can be infinately hot.

For example, steel turns red at roughly 800 degrees C.

:bonk: :bonk:

MI'M not saying it doesn't stop at 100. It's just to condenced.

I guess that would be fine when meauring heat in a scale used for metals.

How ever for human exsistance especialy when relating to weather and cooking there is not enough space.

Yeah your comback is. Well you can get beyond the decimal point. But it's to hard to understand. 32.008 vs 32.8

with farenheight 32 and 32.5 means minimal. How ever on the celcious scale it means a substantial diffeance.

I grew up with farenheight it's much easier to grasp.

I also grew up with inches and feet used in construction and I hate it. That's where metric rocks. How ever human height weight speed and traveling distance is easier in feet miles and miles per hour.

When working on mechincal stuff. Metric is better and I hate standard.

So that's my feelings. They won't change.
