how pricey is a set? anyone had a super deal on them? the write up i got from the local dealer prices up their job @ around 900... Atlantic british has a set for eighty just wires, im looking to find if i can get magnecors' at about that price or better or am i barkin up the wrong tree?

You can get a set for about $95 from Apex Performance?, I think that is the company, I do not know their web address.

I bought mine through Apex

they say champion plugs go very well in disco 2's, im not really on a budget here, just looking to upgrade stuff. whats a good plug to run with magnecors?

Any Iridium plug.

any chance that tuning this up could solve the oxygen sensor codes im getting?
1170 and some code that says low volts sensor circuit

0137
ive posted these before but only got a few replies back, spike suggests tune up, so im getting it together to do that, as my other post says ive had all O2 sensors replaced, computer wired back together (some loose connections found) codes were not present
after that. runs fine tho, no skippies or stutters, just comin up with codes and wanna cure them up.

oh about magnecors what size? 8mm? 7mm?

Start with the tune up.
You said that you DID replace the O2's?

yes have had all of them replaced within 4months, first landrover did the driver side, then i got 2 from atlantic british for the other side, had the neighborhood mechanic do those. drove around due for inspection but knew i couldnt get it to pass with engine light on. then had computer rewired and codes ceased. now have codes that are persistently comin up, so i bought a scanner.
