they look the business, John! nice work!

They’re all rusty(er than the NZ new ones) though. Would’ve been great if the early 2000’s weren’t an utter paint / rustproofing fail from the German marques as they transitioned to water based paints

After donating a Dinan CAI to @Vass we had to figure out what parts they used for their additional cold air source since they dont sell them easy. I know Dinan use alot of OE parts for their mods so i eventually closed in on the likely parts. A quick confirmation with Vass concluded they were indeed E39 6 cylinder airbox boots\grommets. I decided to semi mod mine to re-create theirs after i found some suitable pipe from NZ safety. An additional cold air source cant hurt and im not exactly sure why BMW did not source it from there like the M3 etc, possibly a space or cost issue. Pictures basically explain it, grommet pops out the airbox so its easily removable from the car. As far as temperature goes i didn't do enough logging in varying circumstances to say whether i has a measurable reduction, it wasnt apparent in normal highway driving with a 20 degree air temp and 30-35 IAT with both setups. For what its worth IAT temp reading was only ~5 degrees hotter than ambient air temperature with this installed once you pushed a bit past stuff the license speeds.

Yip still looking. Missed out on a nice e46 330i sedan in Queenstown. There's some nicely optioned ones over there!
