Spark Plug Connectors

Spark Plug Connectors

Hi to all, Recently Welsh Jaguar ran an advert for the correct spark plug connectors for XK's, the straight type, no 90 degree bend in it. I payed my $28 for six, however I am supprised at how short the connectors are. They are not much more than an inch long. I was expecting something about 2.5 inches long. I looked at pictures in Original XK but it is not clear how long they were. This a pretty minor point but can any of the Concours judges comment on it. Thanks, Neville Laing

Neville: I measured a couple original connectors at 1-7/16". 2.5" would definitely be too long. There are also two types of wire connectors: - Most common, I believe, is the one with a brass wood-type screw which threads into the center of the plug wire. - On a second variety, the plug wire insulation must be stripped back a bit and the bare wire is then secured by a set screw in the side of the connector. Can anyone comment on whether the set-screw type connector was originally associated with racing applications? - Dick Cavicke

Hi Neville Laing & all -- I saw Welsh's mailer and ordered them for my Mk IX -- they came today, and are correct shape and length -- BUT they have a red "insert" saying CHAMPION twice around the upper part where the originals had CHAMPION engraved in black (Bakelite) -- I took a red ring off, a 1/16" depression, and NO CHAMPION (or any other lettering) -- so they're NOT the correct ones, especially if you're showing in JCNA concours. I'm staying with my bakelite originals, v. hard to find now, rather than suffer a .1 point loss (x 6) for red that was never there! - Larry Martz

Hi Larry and Dick. The plug connectors I got also have the red "Champion" on them and they are 1 and 7/16 in length. So other than the color they must be pretty close to original. Thanks for the information. - Neville Laing.

Mine are 1-7/16" long, but have no markings at all. - Rob Reilly

I have never had a concours judge comment about the length of the connector, but I have been complemented on the uniformity of the wire length. - Larry J, 660636
