If I recall, this unit is 100% larger than stock. I have had mine for years with no cooling issues in this hot TEXAS climate.


EDIT:

I found the thread....another great tidbit of info from 240M3SRT 's build thread...that should be required reading for all SRT6 owners thinking about modding their cars.

"Stock HE: 1 5/8 x 4 1/2 x 21 3/4, 159 ci of volume
LET HE: 2 1/4 x 5 3/4 x 25 3/4, 327 ci of volume

Please double check my math, but if my calculations are accurate the LET HE is 105% larger than stock. Thats TWICE THE VOLUME!!! Ill be the first to say it didnt look THAT much bigger but the numbers dont lie."
