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.

Get a Crane Allison or Compufire ignition unit. Reliable, and the Crane comes with a CDI box that improves spark quality. The K&N, as I always say when this comes up, is a piece of junk, heavily promoted by sales people who stand to make a big profit, and bought by people easily swayed by advertising. It has FAR less filter area then the stock paper filter, the pores are larger (allowing more and larger particles to pass), requires regular cleaning and oiling, and makes a lot more noise (which everyone knows means the car is faster).
The vacuum taps in the throttle body and the intake manifold are there for a reason. The advance tap draws vacuum when the throttle is open, the retard tap draws vacuum when the throttle is closed, and the ones on the plenum are for the MPS, decel valve, the PCV system, and other users in need of vacuum to adapt themselves to engine conditions. The taps on the air filter are there because they need to input to the aircleaner before the throttle but after the filter. They are NOT vacuum users. Fuel tank evap venting, breather, AAR. The Cap'n
