Hello, there are already Iridium threads here, but they are so, sometimes so out, so here’s my current report: [Introductory: I don’t work for NGK, also not for other accessories industry and have even materially absolutely NIX of this recommendation, but set it anyway, is just my experience, maybe other forum participants also think in this direction (but can only speak for mine, as is with injectors – no idea)]. Was a little dissatisfied n with the warm start behavior of my carburetor FXDX, she also sometimes swallowed herself during constant drive. Had voucher for accessories provider and me decided to redeem this (in the absence of the not exactly luxuriant offer with HD parts) for the not exactly favorable (with Aunt Louise ́s there ́s the just in the offer: 12.95Euro/St.) NGK Iridium candles (DCPR-7EIX at TC88). I installed it yesterday, the result is quite concise according to my current knowledge: nachvo llzugbar improved cold and warm start behavior, clean passage without swallowing and – somehow it does not run as rough as before. Does not want to recommend it to the general public now (never change a running system), but with me they have brought the desired effect.
