The JD HIRs make a dramatic difference in the 100. Much closer to my wife's car xenons. Much whiter and much brighter. And $28 each, they are hard to beat. I ordered the IPF HIR 130 W for the high beams and they will be here this week. The IPFs are $110 for the pair.
Are you going to upgrade the wiring harness before putting in those 130 watt bulbs? I've got the upgrading wiring from Slee in my 80 and I'm still a bit worried about putting in 100 watt high beam bulbs.
