ITB's and foam filters?
Posted: Mon Jul 03, 2017 11:41 pm
I was at a local car show last week with my ITB'd 914. One guy was very interested in my engine modifications so I popped off the drivers side RamAir foam filter to show him the ITB setup a little better. Then I noticed the "roof" of the filter being slightly zinged, can a backfire cause this? It's happned once or twice but I didnt think much of it when it did. I'll post up some later when I get some garage time.
