Whether it's worth it is hard to say. $400 isn't cheap for an intake. At 300 hp , it's probably not cost effective. At 400+ hp levels it makes a lot more sense. But what would a stock intake cost if you didn't have one ? $75- $100 ? In the used market , the cost of the more desirable aluminum intakes has gone up quite a bit post Covid. As for myself , I bought a SM air gap on Black Friday for $140. I realize it is not as good as the Ed air gap. I also have an LD4B which I have owned for ages. I would like to try both and whichever seems to work the best will be good enough for me. As for the weight difference , I weighed a stock 340 intake once. It was 44 lbs. My SM is 17 lbs.
