Where to buy resistive spark plug caps?

[dnb]

I am looking to replace the spark plug shroud thingies on my Griff. I would prefer them to be the resistive kind to damp down some RF interference issues, but the people I have talked to seem to only list the non-resistive kind these days.

Who still sells the resistive kind?

Thanks

ACT?

They were originally fitted to Vauxhalls, so you could try a Vauxhall dealer. I'm guessing 90-96 vintage Cavaliers.

Were on the Astra as well.

This site is most helpful and I have found him cheaper than most:

TVR Power stock these parts. Apparently the NON restistive ones may cause signal interfence to the ECU loom sensors therefore should not be used.
