Hey guys, i was putting on my intake cone filter to day, got it on and everything, had my car parked on a slight hill towards my garage, finished putting the filter on, started my car and let it idle for a bit, i was talking with my dad and a neighbor and my dad was like "anthony is that your car smoking like that...?" i looked and surely enough it was, i was like "what the ****" and revved it a bit, a little more smoke came out when i revved and i was wondering what was going on, i took it around the block and came back, didnt smoke, i set it level in the ally and revved it a little bit, nothing.... i held the revvs at 5000rpm for 10-15secs, no smoke at all, i dont understand what happened, i revved infront of my house and got a friend to watch and there was a very faint coloring to the exhaust, he said it was blue/dark blue but he could barely see it at all, i did revv too 7500rpm that time but after my car was parked on that angle it hasnt smoked, whats going on, anyone know?, is it something to worry about?...
