1. a car never runs as good for daily driving when you put in a colder plug...
2. general rule of thumb for moving to a colder plug is 100 HP over stock, most C32's will never reach that level of performance...

Well I just read their website and an IK20 is the stock heat range for a C32 a IK16 would be hotter than stock, not good here in CA. I think I will go with a IK22 to be safe.

Zepp: I have no personal experience with the IK20, but a couple of people on this forum tried them and were less than thrilled. I can tell you from 20K miles of personal experience (including driving in my black car out in El Centro in July)that a modded C32 runs killer with the IK16, even on 91 octane, and even in hot weather. The IK20 is probably the safer, more conservative plug to run with the C32, but if we wanted safe and conservative we would have all bought Volvos.

From reading Denso's site, it sure sounds like for a modified engine with a high compression ratio, you should at least use 20 or 22 as Zepplin said. If you have added 50+ hp, it sounds like you might get some retarding as engine temperatures increases. It would be nice to get some more opinions on this thread. I've PM'd Vadim to encourage him to contribute. Ideally it would be nice to see dyno with 16 and 20 to see if there is any difference.

from what i remember, Vadim is running the IK16....if someone wants to foot the bill for a set of IK20's, then i will gladly pay for the dyno time to end this debate....if the IK20's are better, then i will gladly relent, as i don't want to run anything that is not optimal for performance...
one thing to note though:
a plugs temperature is not the only thing to take into account when considering which one to run...plug placement in the cylinder head is also something that MUST be considered...sometimes moving to a plug that protrudes farther into the cylinder head or protrudes less, will make a bigger difference in performance and daily driving then the actual temperature rating of a plug...

In looking at replacing the plugs, I noticed that there are some metal shields over the spark plug cover. I assume these are reused with the Magnecor wires. How do the metal shields come off?

Anyone look at the IK16 plugs, after hard miles, under boost?
The IK16 plug are the standard plug for the normal high compression C320.
The C32 is a low static compression motor, with an added blower over the C320. With the blower engaged the effective compression ratio is higher than the C320, but with the blower disengaged, the effective compression ratio is much lower than the C320. Most of the time the C32 blower is not engaged.
The reason to run a colder plug, with extra boost or compression, is to keep the peak temperature of the plug under control, so it does not melt or cause pre-ignition.
The reason, to run a hotter plug is to keep the electrode clean and prevent fouling.
If the plug is too hot, then the timming could get pulled back (retarded), under max boost. Also, it is possible to melt away the electrode or crack the insulator.
I guess most people putting in the IK16 plug, are not tracking (racing) the car for long periods of time and spend most of the time, not in boost.
