Celica Forums General Discussion General Spark Plug change w/ Nitrous

Was thinking of going with nitrous on my GTS, Does anyone know if I should change the stock spark plugs?

How big of a shot are you going? I assume a 50 since you have a GTS. It is recommended that you go colder but I am sure someone who has nitrous can give you a personal experience answer.

Yea...Im tring to do this right so a 50 shot is what I am going with.

Here is some basic info but make sure your smart about what would apply to a celica and what wouldnt like how you need a wet kit etc. http://www.matrixowners.com/forum/viewtopic.php?t=27035

Here's some help:

1. Try to avoid platinum plugs, it will mess up ignition performance. Double Platinum plugs are dangerous too because the platinum chip can separate from the plug and a piece of platinum falling into the combustion chamber could a huge huge disaster.

2. A plug with a short ground electrode is more important than a colder temperature plug and this is why - Temp increases so severely that a longer ground electrode will take longer to conduct the heat away from the tip. This could cause detonation, which you don't want.

3. Try to use a non resistor or iridium plug if possible with the coldest heat range so that the plug can be returned to a safe operating temperature as quickly as possible after the nitrous burst.

4. Also straying from your factory suggested plugs will decrease low load/ low rpm performance. So you will want a set of plugs for daily driving and a set of plugs described above for extreme use. This is required if you listen to anything here, please listen to that.

Hope that helps..
