so i tried a search for this and no luck whatsoever! but i was wondering if anybody on here had tried these frozen spark plugs or something similar
heres the link http://www.lecryo.com/index.html

 

A spark plug sparks. That is all. Waste of money.

 

really.. not to mention getting an extra gallon or 2 gallons a mile on a land rover and then it is getting 13% better fuel economy.. perhaps.. but perhaps what they need to do is ut them on a normal car... that gets an average of 20mpg already and see what it does.... But yes.. spark plugs spark.. some a little better than others.. but freezing a plug is not going to make it spark any better i do not think.. I did not find anywhere on thier site the process or any actual information about the plug itself...

 

Wow. Set of those, some magnets on the fuel line, some water in the evap charcoal canister, and I can quit buying gas altogether.

 

You forgot about the pills that you put in the fuel!

 

and octane booster on a low compression car

 

I can't believe that nobody mentioned the tornado and Splitfires!

 

I wonder if they can chryo my muffler bearings!

 

Probably wouldn't work with blinker fluid though, stuff gets pretty sluggish at subzero temps.

 

alright now has eveyone had there say?? moving on now, my step dad has decided to purchase a set of tese plugs for his spitfire. we will be running tests and comparing them to regular spark plugs. for emission purpases only so i will let you guys know.

 

TWEEEEEET! OK two minutes for piling on!! Seriously, let us know if you see any improvements. How old are the plugs in his spitfire now? Are these new ones platinum. Make sure its an "apples for apples" comparison.

 

i am planning on buying brand new plugs and putting them in right before we go, so that the comparisons can be as close as possible, im stii debating the company but i am most likely going with a platnum plug, any suggestions on company?

 

Bosch platinums.

 

bosch platinum 4's if available.

 

umm bosch platinums are more or less the worst plug for your car..

Set #1.... Bosch Standard Platinums....
each and everyone carbon fouled within 12 miles.

Set #2
Bosch +4's $5.95 a plug

So far all but 2 have lasted 700 miles...

Reason carbon fouling, engine runs extremely rough at stock ignition parameters. All plugs are currently caked in carbon .... Due to in ability to idle and start I advanced the igntion timing to full race spec. 15* @ wot and 35* at idle....

The reason these plugs do this, which i found out when looking through the buyers guide at work is stock AC/Delco plugs run @ a temperature range of 6. 6 being a very very hot plug.. The bosch plugs run at temperature range of 9, being a cold plug.. The only thing colder than platinums is iridium...


Now see when bosch matched up these plugs for our cars they did it by thread size which is 14mm and depth which is .460.. They never matched up the plugs for heat range so if you put the plugs in your small block it will run like ****..!

 

I am very glad you shared that info, Mcdamit. I might have bought those plugs had you not posted what you just did.

 

.The only time you need colder plugs is when you put in a larger cam, increase compression, or obviously nitrous.. Even my 9 degrees of extra timing only got me within 2 heat ranges of what i should be running...

 

Had the same experience with the Bosch plugs in my 88. Took a couple thousand miles before they carbonned up to the point the engine started missing. Really had me puzzled, now I know.

 

I've been using the bosch platinums for years without incident. The heat range of a plug has nothing to do with the conductor used.

 

Red Devil you are actually very much correct about what they are made out of.. Even the bosch plugs in discussion have a copper core.. If anything the plugs are too efficient.

May I ask though, what have you done to your motor? If you haven't really cammed or nitrous'd it out, etc. Pull your number 1 cylinder plug. How much carbon is caked on the damn thing...

 

NGK Iridium's here. No complaints with those, AC Delco or the rapidfires.

 

NGK is a 4... those plugs should be fairly clean if not running a little hot...

 

To bad these guys aren't cryoing rings, bearings, pistons, cranks, rods, and other things that can benefit from a cryo treatment. I don't see how cryoing a spark plug will help, a brake pad maybe but it's doubtful. When you cryo something metal what you're doing is taking out any anomalies in the molecules the metal is made out of and basically making them lay flat against each other. It seems to me if these guys are actually cryo treating this stuff they'de offer a service to cryo treat the stuff that can really be helped by it.

 

Its all BS...


I like the idea of them using this process for engine components though!

That could mean alot lighter and stronger components. Lighter = more power, stronger = less parts coming through hood and fenders!

 

Actually, the Bosch Platinums are a platinum alloy through the core. There electrical conductance sucks as compared to a copper cored plug. Their longevetiy, however, is really good (like most other precious metal plugs).

Currently in the SHO I have Ford plats. that alledge are good to 100K. Since I have to take most of the intake apart to get to the back four plugs, I don't think I'll be getting copper plugs for that soon.

I've used the bosh plats over the course of 12 thirdgens, a few trucks and some odd and end vehicles over the years. Never had a problem with the heat range in any of them except for a motorcycle I was trying them in. :shrug: I have typically used them for their longevetiy when I was using them for one reason or the other. Most all the precious metal plugs are not worth it on these cars unless people plan on overlooking routine maintenance. They SHOULD NOT be used if using an aftermarket ignition (I always have to add that in )

If I want something that actually conducts rather well, be if for a regular tune or for use with an aftermarket ignition, I typically pick up one of the solid copper alloy cored plugs. If I want a 'little extra' I index the plugs and cut back the strap. You want the least inline resistance when using an aftermarket ignition. (Don't get me started on the alleged 'low resistance' crapola wires MSD and others sell.)

That all said, cryogenically treating metals generally make the metal crystals align in a more uniform, compact and denser molecular structure thus increasing it's potential electrical conductivity. Will you be ably to see the difference in a typical engine that we see on these forums? I highly doubt it. The figures I could find ranged from a 6%-10% increase in conductance of cryogenically treated pure copper.

 

I do agree with you as far as longevity.. I can't post the bosch reference book from work but here:

Bosch Platinum+4 Spark Plugs: BCH-4449 - summitracing.com


Umm my complaint with them is that aren't properly matched, and usually aren't hot enough to keep themselves clean.. The carbon fouling is amazing on these plugs....


Edit.. that just sparked my interest.. im gonna hit the books...

 

Just get AC Delco plugs, they were designed for your application and they're what GM put in, not some BMW mercedes plug. BTW, if your smart you won't listen to mcdamit, ask the guys over at 3GO why.
