as the sayin goes, you get wat you paid for.
a couple people on here have got the just jap stealth cooler for i think $550 and have given mixed responses. some say its good, some say the quality is poor but it still does the job.
instead of getting a cheaper one and having hassels, as mentioned, the ARC "stealth" style is a great cooler but with a LARGE price tag. think around $1600?
there are others such as the GREDDY one. http://www.skylinesaustralia.com/forums/Gr...le-t231160.html
this does mean cutting a hole on the driver side front section of the engine bay.
go quality not cheap ones IMO
