for r/t owners with the spark knock blues that just won't go away even with 93 octane. use a 180-185 thermostat factory cpu programmed to run best at 182 degrees. reason for spark knock with 195 is coolant pocketing and combustion chamber running to hot.

also get rid of the C series plugs they don't have a broad enough heat range to run our beloved r/t 5.9. switch to a N series plug but first remove spark plug sleeves. a RN9YC at the track and RN11Yc for the street is a good starting point for stock or slightly modified engine. remember the more mods you have the colder the plug you should use.

also if your running cold air induction scrap it it isn't helping as much as you think. the best application for the 5.9 is edelbrock breather part number 1221 and adapter 8093 more cold air flows through this than cold air induction.

good exhaust flow can be achieved by using 1992 exhaust manifolds and y pipe. 92 manifolds have a 2 1/8 opening r/t manifolds 1 7/8 opening you do the math. passenger side part number 53006618 and drivers side part number 53006617.

h o l y ERRONEOUS POST LOL

"all together now"
the knock is caused by your blown belly pan gasket on your beer barrel intake 99.9% of the time....look in your tb with a flashlight..see the little puddle of oil? ..r/t ers have a better way. just ask.

so how long have you been driving with the knock and searching for solutions?

180 stat..good.
stock plugs or one step colder autolite 3923's..good...theres other alternatives.

scrap the cold air induction...insanity...use kn gen2..maybe find an extra large filter for it.
remember ..the cooler the air..the more hp you get.

take yourself to the delphi r/t forum..and/or join the dakrt club at yahoo before it's too late.

thank me later.
