K&N induction

[michaedo]

Merry Christmas to me! Attempted to help
Greasedlightning with his leaking oil filter
and it cost me money. Ain't that the way.
Took a little trimming on the heater box to
fit but looks like it belongs there. Got the
black paint off but the polishing will have
to wait. Zoom-zoom....

Looks Good!

Very, very nice fabrication job and, while your fitment is very organized and neat in appearance, you do realize that your K&N air filter is located in the very hottest part of the underhood area, right?

Radiated hot air from the exhaust manifold and radiator rises and is pushed back to that very spot up against the bottom of the closed hood with nowhere to go but into your engine through that filter you bought specifically for its hi-flow! One of the things on which Opel spent considerable time and effort and, which cannot be improved upon to any significant extent, is their engine fresh air intakes.

I'm an admittedly biased, "fresh, cold intake air" proponent and would strongly suggest orienting the filter and snorkel toward the front and beside the radiator to take advantage of this "factory" fresh, cold air already provided for . . . squarish thru-hole next to radiator in your second pic . . . it's very much cooler there!!

I can attest first-hand that all the time and effort it took to modify my '69 Kadett dual DFO 'sprint' intake for 'cold air based on Opel designs' was well worth it . . . below!

Yeah, my initial install had it running to the front but
a clearance problem reared it's ugly head between the
bulging rubber thingy (mechanical term) and the hood.
Maybe fabrication of a box to surround the air filter is
in order. Got the day off today, think I'll see what can
be done.

Hello again listers,
Just finished this week's project. As pointed out a last week,
I've located my "cool air intake" in the hottest part of the
engine bay. So....presented is my very first attempt at fiberglas
fabrication. I still need to get a rubber gasket of some kind to
surround the stem of the air cleaner going into the box. Had
to fit, start, fit, start, etc. to make sure there was
clearance-a-plenty around the air cleaner itself during running/
idling. I used that green foam stuff floral shops stick flowers in,
shaped it, then glassed it over, then pulled the green foam out.
So, except for some air coming in around the front, all air is now
coming in from the vent at the top/back of the hood. (I hope.)

Here's another little hint for you, now that you made that nice little box for the filter, get some fine, screen door mesh and cut a piece to fit over that entire area, and use the rubber hood seal to hold it to the heater/airfilter box.
Keeps out all kinds of trash.

Yeah, thanks Gene, I usually park under a tree at work that
has little black beans that tend to fall into those vent holes.
Seems like they actually aim for those holes. Think I'll make a
run to the hardware store tomorrow.

That actually might do what you intend for it to do. It looks a lot better than the first time. Have you been able to tell any difference?
