- Bosch triple platinum (BADDDDDDDDDDDDDDDD)
- Ralliart wires (good items, but no reason to buy them)
- Denso Iridium (not gonna say bad, but why these instead of regular NGK?)
Ok, so we have a whole slew of useless or nearly useless mods here, so it's hard to diagnose what's going on with your car. Here are my suggestions in order:
1) Get a set of NGK BPR7ES spark plugs for $1.40/ea, gap to .26 and install those
2) Re-install stock plugs wires (just for now)
3) Re-install stock intake (use AEM after you get tuned)
4) Re-install stock BOV (sell and get a JDM MR DV or Forge RS)
If your car doesn't run properly after this, then you might have a big issue, but it will allows us to troubleshoot more easily. If your car returns to normal, then re-install the Ralliart wires and ensure things work fine. If so, then go forth and conquer while following my other suggestions. Also, sell that 2.5" cat-back if anyone will buy it, and then get a nice 3" exhaust (TBE preferable).

What the hell is wrong with those guys. Do you not have a manual for your Evo? Man, .040, no wonder! I can't imagine listening to those half-wits at places like that. They know how to put plastic wheel covers on Toyota Corollas - do not rely on them for anything on your Evo!
You need to be gapped to .026 or so like I said (.26/.026, whatever, it's not like you can really gap them by a factor of 10 higher). You aren't supposed to re-gap Iridium plugs to begin with, so I don't know what's up with that.
Please, both of you, do what I've already said twice. GET NGK BPR7ES FOR ONLY $1.40 EACH AND GAP THEM TO .026, PLEASE! This take like one day to get done. The iridiums can work, but I wouldn't rely on them if they've been tampered with already.

I called Pep Boys, Auto Zone, and Checkers and neither of them carry the NGK BPR7ES. Checkers can order them at 2.99 a plug (which is acceptable to me to fix this problem). I will order those ASAP, and fix this before I run into bigger problems. Thank you so much. I am def. comming to you guys before I do anything from now on. Any other advice?
Yes, always come to us first before doing anything. I already gave you a lot of advice that you need to follow. It is VERY UNFORTUNATE that you trashed your stock intake and stock BOV. Did you just throw them away? The stock BOV was _NOT_ part of the stock intake, so I don't know why that got thrown away. Please, whatever you do from now on, NEVER throw away your stock parts. Seriously, sell that BOV and the HKS EIDS, then get the parts at this link:
