K & N After Market/Ignitor Ignition, Air Filter & Timing Options

[Vinson]

Is anyone out there using the after market K & N air filter offered by Automobile Atlanta for there 1975 2.0 fuel injection? I am wondering if this system works good and what the pros and cons might be. I am also interested in knowing if anyone is using the ignitor electronic conversion kit for the same engine? I saw a really interesting article in Excellence about converting to a modern ignition system. I am wondering if these really work on a stock engine and fuel injection or should i expect to have to modify more? I appreciate all your help. Thanks everyone.

Stupid off the wall question to satisfy my curiosity:

Why are some vacuum taps at the end of an airbox and others down on the throttle body? Different level of vacuum? Although it seems it should be the same, unless the air accelerates and is moving faster down there?

I thought about putting something like this together... not necessarily expecting a performance increase, but I like the cleaner setup. My car is desmogged and I don't need all of the vacuum taps. I was thinking it would be easiest to put all the taps in the end cover and leave the intake tube smooth... but if the location is important I don't want to experiment.
