Looking at the engine bay of any modern "rice rocket" tells you that a great deal of improvement has been made from days our Opels were made especially in the area of cold air intake.
I want to streamline my air intake on my FI 75 sportwagon and here are some thoughts:
1) Replace stock the air intake using 3" smooth tubing coming off the MAF and rerouting it back towards the firewall shelf that is underneath the plastic cowl vent that seals against the underside of the engine hood.
2) Cut a 3" hole in the underside of the vent to take advantage of the air that gets forced off the hood and windshield through the slots cut in the hood
3) Build a lightweight box that would rest on the shelf, house the air filter and permit the air to travel through the bottom of the "cut-out". into the filter without sucking in hot engine air.
QUESTIONS
If I cut this hole in the plastic vent and built a box to house the filter would I be introducing engine fumes into the cabin?
How might I be able to eliminate water from rain or car washing going into the filter area?
Your thoughts are appreciated
