spark plug question
hi all
was gonna change my spark plugs but i have spoken to my mate and he said that i need 2 pairs of different plugs 2 for rotors and two plugs for something else but they MUST be different...
i got these ones:

and they all the same ...can i still replace them? is it true that they must be different?
cheers

i have replaced the plugs, and IMHO car runs much smoother i was always getting it up to over 6k revs and it was kinda breaking up...now its all fine (i think) even idle sounds better but this is what someone else said about my plugs:
is this true?
btw this are my plugs:

is this all true? should i change my plugs even if i proper hammer my car?
unless you have a car with a big power increase you never need look any further than NGK 9's, also plugs with the heat range shown on the link are far to cold for normal engines and may well led to flooding,
Also please do not buy the Denso plugs as these have killed Rotarys over here because of the end of the plug falling off into the engine, destroying a tip and wiping out the engine.
An ex Mazda technician told me that Denso actually know they have a problem "sometimes" just with the Rotary because the Rotary combustion sets up something like an harmonic frequency that shatters the end of the plug where as the NGK can copes with out a problem

Which would make those equivalent to about a heat range 11. Very good for a race car or serious drag car, maybe not so good for a daily driver.

Using a plug too cold can lead to worse performance, worse gas mileage and quick fouling. I have not really heard too many bad things about Denso plugs, but I typically stick with NGK myself. Here's some research on various plugs:
