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.

Not for nothing. We AX and DE our 914 every week and use K&N filter stock on it. We found it cuts 3 sec in comparison to the air box which gets very hot. That large hot air box, heats up the air inside resulting in the power lose. Having such a large air box with the throttle body plate the size of the silver dollar, does not make any sense. The filter sells way to cheap to have any noticeable financial gain for the dealer. As far as going to the hardware store and building one yourself, go ahead. The elbow is a part of the complex pipe system, and not sold separately in the stores. We special-order this elbow from the drain-pipe manufacturer. What ever you will find in the store will look strikingly similar, but will not clear the rain tray.


As far as Crain Cams fireball 700 or 3000 point replacement. We are bitter disapointed with this box's performance for the racing purposes. It makes the car run too smooth. No aggressive pick up. The chip inside the box plays with timing. Between vacuum advance and the chip it makes performance driving impossible. Pertronix on the other hand does the job "Right". Just need to install hotter coil, turn your altimeter on the DME 3 clicks forward to enrich the mixture..and you will be "cooking".
