OEM v6 plugs

I put some non-OEM plugs in last service, they're a bit rubbish though. Now I can't remember what the original plugs were other than they were 2 prong. Looking for somewhere online to buy them too.

According to my Indy, they ARE the same plugs as the TU 1.1 engines!!!!!

and probably EQUIUM, but NGK are a very good brand

Giving the awkward nature of the rear bank of v6 plugs would it not be prudent to put a set of long life plugs back there?

This is how Mitsubishi did it with the V6 FTO, the front bank were standard plugs the back bank were long life iridium tipped thingies, service interval for the back was double that of the front.

As long as the heat rating is correct, and the gap is adjusted right, and your sticking to a good brand, like NGK there should be nothing else to it no?

oh right that should be easier to get hold of, do you know their part number?

I tried NGK last time and it misfires on idle a bit. From what I remember plugs need to be 2 prong for this engine to unfoul themselves, ones I had were 1 prong. 4 prong is supposed to suffer misfire from the spark being hidden. Or so i read anyway

I've been through just about every type of plug from Bosch to Denso to NGK, platinum, iridium, u groove, multi prong and single prong. Never had any trouble with any of them. Currently have the four prong NGK ones which seem absolutely fine. Halfords only do them in fours but you can get them on ebay individually.

Or try here

for a range of options

I find a good thrash keeps the plugs from fouling

oh, what do you gap the single ones to stempy IIRC the ones in the car when I got it were NGK 0.9-1.0

I use the OEM EQUIUM ones in mine and I have to confess that in 12,000 miles I cannot fault them. They're plugs, they spark. GSF sell them. They're well priced and they are what PSA used when they made the car.

I cannot see any advantage whatsoever in using a "designer" plug and if the NGK plugs are anything like their glowplugs then I'll steer clear of them, thanks..

Indeed they are Paul, PSA used one plug right across the range all the way from the tiniest TU right up to the V6!!!!

I always set them to .85mm

I don't think that there is anything wrong with NGK plugs. They have not missed a beat in 110,000 miles for me. I change them at about 25,000 miles, although the rear 3 must have done 40,000 miles when I got the car and were looking a bit worn.

Speaking of plugs, does inlet manifold have to be removed to replace rear bank?

Yes, sadly it does

It's not a difficult job but it's always a good idea to have a new manifold gasket on standby as the old one may not be reusable...
