Heat sink paste

[fastfraser]

I'm doing a lot of my 12,000 miles service myself and one of the things I'm doing is changing the plugs NGK DCPR9E with a gap of 0.7-0.8.

Here's the question do i have to add the heat sink paste to the threads?

What is heat sink paste and what does it do ?:dontknow:


Thanks in advance for your replies.

It is a strange recommendation for sure. That fact alone is enough to convince me there must be a reason for it. Heat sink paste is used in electronics. In computers for example we use it between the processor and the heatsink that sits on top of it. It basically fills all of the "pores" if you will and allows for better transfer of heat between the two parts. You should be able to get a tube of paste at Radio Shack.

BRP has a version also and dealer should have it :ani29:

Heat sink paste is essential. The Radio Shack P/N 276-1372A is a silicone based compound like the BRP recommended P2 paste. It costs $3 or $4 USD for a small tube, enough for a few plug changes. The BRP paste costs $40 USD for a very large tube. Most dealers will have to order it. Other electronics outlets may have an equivalent, if you do not have Radio Shack stores in Canada.

The paste you want to use...

has a ceramic powder in it. The ceramic powder helps the plug make better contact with the thread in the heads which helps get the heat off the plug. /Ken

Would a high quality high temp anti-seize product work of similar benefit, it may not be exactly whats recommended but will it work?:helpsmilie::dontknow:

Don't do this! The heat transfer properties are not nearly as good, and anti-sieze compounds are notorious for causing corrosion between dissimilar metals.

Thanks Scotty thats why I ask thanks.

high temp anti-seize

I am on my second rotation of plugs ( changed every 3000 miles ) and have been using high temp anti-seize from NAPA -no problems.

pathfinderJoe...

are you using the iridium plugs that is being discussed on this site? I just received three sets to try./ ken

 

[pathfinderjoe]

Sorry - No - I did not see the reference to iridium plugs on this thresd.

crap, now i gotta take the spark plugs i just replaced and put some heatsink paste on them. there is no problem reinstalling same spark plug, right?

No problem re installing them. You know all the years i've been changing plugs i never heard of using heat sink paste. But when i got my iridium plugs from Autozone the first thing they said was, do you want some heat sink paste to go with them? Sought of like at, Mickey's D's do you want fries with that. Always something new to keep you on your toes.

Rotax requires it on their aircraft engines as well.
The Radio Shack stuff has the exact same specs as the BRP stuff.:2thumbs:

:yikes: Just picked up 1.2 oz. heat sink paste from the Source ( Canadian Div. of Radio Shack ) $12.00 bucks ! Thats more then i paid for the gosh darn plugs.

Beats $40 USD for the BRP paste.

:agree:

The Ceramic paste is...

is available at Radio shack here in FL for $6. It is white in appearance, contains ceramic powder and is in a little syringe. When applied properly there is probably enough for 6 spark plugs. /Ken

I went to radio shack to get a tube of the heat sink paste and right beside it was a much smaller thermal compound (the expensive one $10) so I went with this one, they told me it's better than the $4 paste. After I got home I looked at the back it says 99.9% pure silver, can I use this one or I need the other $4 silicone tube one

The BRP heat sink paste is P12 Silicone (Wacker Silicones).
