don't buy. it's a resistor that costs about 20p to buy and they don't work

the resistormod in the RON plug does make a difference, but only in the 2.0 8v engines to my knowledge, its possible with different resistances to up the fuelling or adjust the timing, it certainly worked when I changed the one on my corsa, I went for a 5% increase in fuelling across the range, revs picked up a bit quicker and seemed to idle better, but also the emissions went up slightly, and when really booting it was a trace of black smoke, this went when the ron plug was replaced, and the fuel consumpyion also improved when it was removed.

knew I had the data on pc somewhere, this all came about when the calibra boys tried switching the plug round from A to B, or maybe the other way??
but here is the list of what does what, but it does only apply to the 2.0 8V engines as listed
The table below shows the changes made by each resistance value-V-Octane rating for the three basic 8 valve engines...
KEY
1= Basic value
2= Idle speed increase by 100rpm
3= +5% fuel acceleration enrichment
4= +5% fuel enrichment throughout range
5= Ignition retarded by 5 deg throughout rev/load range.
2.0SE/ SER/ SEH non cat
91 Ron N/A
95 Ron 220 =1
1200 =3/4
2200 =2
4700 =2/3/4
Infinity=2/3/4/5
98 Ron 470 =1
750 =2
2.0 NE non-cat
91 Ron zero ohms =1
infinity =2
95 Ron 220 ohms =1
1200 =3/4
2200 =2
4700 =2/3/4
750 =2/3/4/5
98 Ron 470 ohms =1
2.0 NE cat
91 Ron Zero =1
Infinity =2
750 =2/3/5
95 Ron 220 =1
1200 =3
2200 =2
4700 =2/3
