An aftermarket turbo intercooler will go a long way towards cooling down your engine and improving performance.  These are typically mounted in front of and below the radiator.

You can get a lower temp thrmostat and a big front mount intercooler. Better performance and the big front mount just looks good.

If you are needing to cool down the engine theres something wrong man. A stock SRT-4 should not be overheating unless you have one heavy foot. Details or reason why its overheating? And as far as a larger FMIC goes, if youre doing the install yourself you may as well go the whole nine yards and invest in a hardpipe with a welded flange on it for mounting a HKS SSQV or a Turbo XS RFL BOv. If youre really serious about decreasing the Temp, make yourself an Intercooler sprayer.

The stock intercooler is efficient even up to the Mopar Stage 3.  The hood scoop keeps things cool as well.  But yeah...making an intercooler sprayer or buying a water injection kit are two options...you can always upgrade to a large fmic....those always look cool...lol.

why would you need to waste money on a front mount and who ever mentioned a blow off valve to decrease the temp is dumb all it does is make a cool sound lol oh and by the way its a neon that is where you went wrong my grandma drives one of those

get an aftermarket intercooler

your penis is small and that baby is ugly

thats no what your mom said and fuck you that is my son you prick maybe if you were a man and responsible and oh had not such a low sperm count you could have one

larger fron mount intercooler will help
also an aftermarket ligthweight radiator, such as Koyo, will save you a little wieght and cool better
an oil cooler would be helpful too
cooler oil keeps the it running longer
