Hi everyone,
I took my intake manifold off today, and I noticed that there is a sandy material in the intake runners of my heads, as well as inside my fast intake. Where do you think this is comming from? I believe there could be two options.
1. My engine is detonating itself to death.
2. Dirt is making its way through my air filter. My air filter is in a place where it could be exposed to road dirt
That puts me into a little bit of a pinch, this engine is swapped into a gbody monte carlo. So I really don't have a way to run a factory paper filter. Does anyone make a good quality paper cone filter?
There are FOAM overfilters for most of the K&N style, they work well and don't impact the air flow.
For race cars I go to http://itgairfilters.com/ Their filter foam (Still needs oiled) is like what most dirt bikes use, I've run them on dirt track cars and never had anything get through..
