Carried out a search but couldn't find the info. I want to use NGK Iridiums. The plugs I have at the moment are NGK BP7ES and the equivalents show as BPR7EIX however whenever I do a search for these it states that are not compatible with my model Car is 1980 308 GTSi 2V.
Not sure about on the two valves but BPR7EIX is what I use on my QV. I think as long as you match the original heat range for the Iridium, it should be ok.
Says who? If you go to the NGK website (www.ngksparkplugs.com) and look up your car in the application guide, it specifically lists BPR7EIX (and BPR7ES) as being correct for your model (BP7ES is a non-resistor type plug that is A-OK to use on your model, but spark plug manufacturers have gone to typically only making resistor type plugs in modern times).
On my 82 2v. I use BP6ES. The extenders are 0 ohm and the wires are about 500/ohm/ft. I have also use 7s
I use NGK BPR7EIX in my UK 1978 2v dry sump carb GTB, they're excellent. If you use Amazon, Ebay or car shop compatibility check they will never veer from original spec, probably Champion N7Y, so will never say any NGK plug is okay.
What was the original Champion plugs recommended for a 1985 308 QV? I would like to have a set so I can add it to my Toolkit.
Anybody else notice inductive pickup devices like tachs & timing lights work appreciably better without resistor plugs? I have several inductive devices that were really flaky, or flat-out wouldn't function right with resistor plugs & resistor wires & resistor plug extenders.
