Do I need to gap the NGK IX Iridium plug (BKR5EIX-11)?

Just got a set of 4 NGK IX Iridium plugs (BKR5EIX-11, 6.99 each), it is factory gapped at .044 inch, the spec for the SR20DE engine is .035 inch, just wonder if I should leave alone at .044 inch or re-gap it to .035 inch, Has anyone use the NGK IX plug before, any input?

I don't think you can gap those plugs. You'll mess up some kind of coating or something. Not sure though, someone else will have to confirm.
