In El Paso county in colorado springs the state does no require emissions testing. I just want to know if anyone has taken an emissions test with E 85 and how did they do. Do you need to run a cat with E 85 or is it clean enough not to require one.
Also to add to this topic is the issue of spark plugs. I currently bought another set of stock plugs because the NGK plugs I bought for some stupid rediculious price kept falling out of gap and caused a shit load of problems. Will the stock plugs work well with E-85 or do I need to go and buy expensive NGK plugs again?
First off, NGK plugs are not expensive - they are extremely cheap if you get copper. The stock plugs are Iridium and even more expensive than the NGK Iridium. You aren't supposed to re-gap Iridium plugs either. Coppers, however, can be gapped easily and safely. With E-85, you run high boost, so you should run coppers anyway. Get BR8ES (or BPR8ES or BPR7ES or BR7ES) and gap them to .018-.019 or so. Buy packs of 10 like I do and keep a bunch spare. They are very cheap but won't last as long as Iridiums.
Any store that sells plugs like Advanced Auto or Autozone. Those places usually have them in stock, but if not, they can either get them from the warehouse or from another store in the area. Very cheap...
Well, they last longer - that's why they are more expensive. I probably use the same dollar value of copper plugs as someone who uses Iridium. I'm at 29k - well below the useful life of Iridiums (depending on mods/racing/fuel/etc) - and I've probably changed plugs 15 times.
