Title: Re: sparkplugs Post by: Thotos on August 04, 2010, 01:29:33 PM What are the best plugs for the twincam with unleaded petrol , n9y ? I don't think the petrol has much to do with it but N9Y are the wrong ones; they are meant for the OHV engines and later single cams. I believe the correct spark plugs for the twincams are: Champion: N6Y (better N6YC best N6YCC). Not easy to find these days so some people suggest changing to N7YC or N7YCC. NGK: BP8ES which are very difficult to get hold of. BP6ES (or BPR6ES, the 'R' is for 'Resistor' which acts as a suppressor for radio interference) are equivalent to N9Y so I'd say not the right ones for a Twin cam. Having said that, I have seen them listed as suitable for Fiat Twin cams. By the way, if you have good quality suppressed HT leads then it's better to go for non-suppressed spark plugs (without "R" in the name) Bosh: W200T30 These are meant to be equivalent to Champion N6Y but I found them to be useless in my 2000 Twin cam lasting only about 3000 miles so I'd strongly recommend not going for these. But I am now using Bosch Super-4 W56 spark plugs in my Fiat with good results. W56 plugs are also getting hard to find these days but the suppressed equivalent (WR56) are still readily available.

Title: Re: sparkplugs Post by: TOAD on August 04, 2010, 05:43:44 PM Hi Chaps,
NGK BPR6ES were the standard Plugs for both engines, the Compressions are the same. I didn't know anyone still used Champion Plugs after they had such a bad name for braking down. So, BPR6ES for normal/slow driving BPR7EV for more spirited driving 140/150ish BPR8?? for Moded engines over this power. So I Think Roger............... ;D Title: Re: sparkplugs Post by: miro-1980 on August 08, 2010, 01:56:39 AM Roger , I think the same...
For really highly tuned engines 160-190 bhp I would recommend a NGK "9" Normal driving ONLY: NGK BPR6ES Miro Title: Re: sparkplugs Post by: 124 man on August 08, 2010, 05:03:50 PM How about denso w20 epu ?
Title: Re: sparkplugs Post by: TOAD on August 08, 2010, 07:35:59 PM I thought Denso was ether part of NGK or of a similar quality. Any body know different?
