geoffbeaumont Posted October 30, 2005 Share Posted October 30, 2005 For an 3.5 Efi (1988ish) Everyone seems to recommend NGK for the V8s. Can't remember the exact model but if you have a dig around on RPI's web site I'm pretty sure they've got a bit that tells you. Quote Link to comment Share on other sites More sharing options...
Tangoman Posted October 30, 2005 Share Posted October 30, 2005 Have used others but found NGK BPR6ES to be the best recommended by Nige Barker But cant find where they go on the new engine Quote Link to comment Share on other sites More sharing options...
Niall_CSK Posted October 31, 2005 Share Posted October 31, 2005 IMHO I found the Bosches to be better than Champions but I now swear by Denso's since a local engine tuner turn me on to them. They were half the price of Champs and a third of the price of Bosch, way outperformed both on LPG and I saw the proof on a "Bear" tester, still going strong 15k later, the Champs lasted 3.5 before starting to fail. Sorry I can't check numbers right now. Quote Link to comment Share on other sites More sharing options...

Niall_CSK Posted November 1, 2005 Share Posted November 1, 2005 I can't remember the name or the phone number but it's in Irvine. Take the old Gailes road past Comet & (Harry Fairbairn) BMW garage towards Troon, take the left road at the Motor Factors sign posted for the small industrial estate, go to the end of the road just before the railway line and turn left into the estate (lockup type) turn right and he is second or third garage on the right hand side. Very helpful chap, think a set of 8 were 22 quid. Quote Link to comment Share on other sites More sharing options...

DEANO3528 Posted November 7, 2005 Share Posted November 7, 2005 NGK V-Grooves made my 8 run really sweet. Quote Link to comment Share on other sites More sharing options...
Ex Member Posted November 8, 2005 Share Posted November 8, 2005 NGK Iridiums are the best. You asked for the best, so don't complain about the cost. But yes, the NGK V-grooves will work just as well in a Rover V8 although the Iridiums should last forever. Quote Link to comment Share on other sites More sharing options...
rangerovervoguese39 Posted May 20, 2007 Share Posted May 20, 2007 I just got 8 Denso's (although they where all about the same price and a choice of loads of different makes) at www.spark-plugs.co.uk for 15 delivered! Quote Link to comment Share on other sites More sharing options...

willfromsussex Posted June 30, 2007 Share Posted June 30, 2007 Just to say, Densos are also my favorite plug. I have had NGKs fail for no apparent reason, but never had a prob with a Denso Quote Link to comment Share on other sites More sharing options...
Ally V8 Posted June 30, 2007 Share Posted June 30, 2007 NGK BPR6ES is all you need, I only pay 94p each for them and have no problems - but I do buy 80-100 at a time. Quote Link to comment Share on other sites More sharing options...

tillmannz Posted September 3, 2009 Share Posted September 3, 2009 Hi! How much is the gap of BPR6ES what you use?6mm,8mm,..or???? Quote Link to comment Share on other sites More sharing options...
g&t Posted September 17, 2009 Share Posted September 17, 2009 Strange how owner's experiences differ: I've had four RRC's, three 3.5's & one 3.9 (never again!) & have always used Champions without any problems. Invoices that came with my last 3.5efi detailed problems with 'misfiring' cured by replacing plugs on three occassions & reference to the part nos. showed the plugs to be NGK. None of the 3.5's have run on LPG or been off-roaded so perhaps that makes a difference(?) Strangely enough a NGK plug is specified for my lawnmower & that never lasts for more than a couple of seasons either! Quote Link to comment Share on other sites More sharing options...
geoffbeaumont Posted September 18, 2009 Share Posted September 18, 2009 NGK BP6ES are normally recommended, and what I always used in the 3.9 and 3.5, without any problems whatsover (related to the plugs anyway...). That was with LPG, originally on the OEM dizzy system then later with EDIS and a nice big spark gap Changed when they were due, never had to change them earlier. Avoid fancy plugs - the RV8 doesn't seem to like them much. Quote Link to comment Share on other sites More sharing options...
