First off, that intake was not made specifically for an MS3. If you ask me, I would not have just put any intake on this beautiful car of ours. But hey, to each his own. Check the MAF wiring harness and make sure they have slack so when you do punch it or have some fun it has enough to move with the engine.
yeah I think it might be the intake. I might just get a mazdaspeed one to replace what I have now. Plus I notice I need to clean the filter.
