As suggested by Hugh-CE get onto ClubCJ. There is a heap of info there for you. May even find someone willing to swap CJ bumper for CF bumper and if both cars same colour save, heaps more.
What color is your car?
By the way, suggest you buy a RallyArt induction snorkel $175 new from Mitsu straight replacement. No warranty issues and unbelievable, well almost but definite benefit.
then add a bit more for further improved breathing as in picture of mine or alternatives on ClubCJ. Existing snorkel is restrictive.
