I'm redoing a messed up intake system. The previous intake consisted of ten inches of tube coming off the TB and connecting to a cone filter that sat right above the exhaust manifold. Now I have added a bend and about twelve inches of tube to get the filter down where it should be. However, the MAF is way back at the TB end. Rerouting it would be a pain. The question is, will having the MAF by the TB instead of closer to the filter affect its reading? If so, is it enough to worry about?

 

no it will be better and get better throttle response
