Iridium plugs??

[rx7_bhp500]

never seen NGK R740s or R725s do that been using them for years as many other high powered Rotaries.

Hearing and seeing are two different things

If I happen to meet more owners using the iridium plugs and reliably then I might have a different point of view.

taken from the kiwi rotary forum :
"***WARNING DON\'T USE THE \'NEW\' EIX RANGE OF IRIDIUM PLUGS or ANY PLATINUM PLUGS***
They use a friction weld to hold the Iridium/ PLATINUM tip in place, this can fail in turbo engines with catastrophic results....."

- its just what I heard...

whats new EIX range and NGK 742s (these have been around for donky years)got to do with each other?, these plugs get used by RE-A , Feed, HKS in Japan, etc etc anyway cant be bothered to argue the toss , use what every you want Dude , I will carry on using my NGKs quite happly

Right just had a look on that post on kIWI Forum, they are talking about a diiferent range of plugs EIX are the "R7" series!
EIX are designed just for piston engines hell you can even buy these in Halfords, so please mate stop spreading misinformation on this forum over two different types of plugs.

R742 v EIX plugs NOT the same plug.
R742s were designed for rotary turbo engines and their high heat hence the"R" bit in the model number

[BlitzBoy]

and here is a pictures showing the difference between the EIX v the NGK/HKS

EIX on the left, NGK/HKS on the right

as you can see twoo totally different plugs, plus if you want to use EIX you would have to use a modified plug socket to fit them

stop by boots and ask for some chill pills...

[BlitzBoy]

ive been using the B9EGV plugs in mine for about 2 years now since its been modded with good results and no problems and they only cost £32 a set, gonna be going up to B10EGV now ive gone single turbo.  Theres a few guys who live near me who have been running single turbo FD\'s for quite a while and they recommended the B9EGV plugs to me.  As said above you have to modify the socket to get them in :Thumbsup!

[BlitzBoy]

do they do an 11 heat range Chris?

yep, same here:Thumbsup! 9\'s all round for me with no issues and in this cold weather they perform better.  In the summer its 9\'s and 10\'s

[chrisJDM]

im not sure i always get them from here //www.spark-plugs.co.uk so will take a look

[chrisJDM]

ok just checked and they do, if you type in b11egv in the part search on the left it will find them.  Â£6.79 a plug :Thumbs-up

nice, as the yen is screwed at the mo, maybe a good alternative for me to use those for the time being and save my 742s for the drag work
