version 1 paper style filter, with arc intake chamber. i did not notice any heat soak i had many differnt intakes and this one was by far the best. also to add have no problems with the so called A/C line being in the way. reason why im selling is because im going with the spoon front bumper so i need the intake to match up with the intake hole on the bumper. willing to trade for authentic spoon snorkle. looking for 450 obo located in calgary!
