fla 9 Posted September 24, 2007 Does anyone know the pipe internal diamter of the cooling pipe that runs from the VR crackpipe to the oil cooler and then to the block? Any particular pipe material recommended? I've installed my mocal and deleted the crappy OEM cooler but i want a straight piece of hose rather than two joined pieces. Just looks a lot neater. Many thanks Quote Share this post Link to post Share on other sites
Supercharged 2 Posted September 24, 2007 It's probably 16mm ID (5/8") but maybe 19... (the bottom of the exp tank is 16mm, does it look the same size?) All standard size stuff as i've recently round out, halfords sell it off the reel or you can get Goodyear stuff from specialists (look on eBay for heater hose) Quote Share this post Link to post Share on other sites
fla 9 Posted September 26, 2007 Its 13mm id, just checked. For those installing a mical, its a good idea to replace the two pipes with a single piece, rather than joining them. If nothing, it looks a lot neater. Quote Share this post Link to post Share on other sites
