Spark Plugs are special order? Say it isn't so

There hasn't been a lot of love here for the Champion brand.

If you are looking for the Champion N7Y, I think most of us would rather opt for the NGK BP7ES (or maybe BP6ES if you are not hitting triple digit speeds often).

If you are dead-set on using the Champion brand, you might have better luck finding N7YC (which is just the updated version of N7Y with Champion's "Copper" construction).

 

You shouldn't have a big problem finding that NGK BP6ES locally, but many of us order our NGK plugs on-line from www.clubplug.net (especially for the more expensive IX type).

For US driving, going to the "6" NGK heat range is normal practice, and many even go to the "5" NGK heat range, but at $1.91 each I think you could try a set of the BP6ES first without much regret. If you still have fouling problems, try the "5"s or the NGK BPR6EIX style.

But please confirm which Champion number that you were/are presently using/seeking just to be clear.

 

I'm pretty sure you are correct on the NGK numbers. NGK & Champion heat range numbers run opposite from one another.

If you are fouling out / loading up, I would go with an NGK heat range of 5. Also, I strongly reccomend the NGK and Nippon Denso Iridium tip plugs.

I am a big fan of the NGK plugs, use the BP6ES and they work well. With NGK, the lower the number, the hotter the plug.

I run NGK BP5es in my 400i - no fouling even though my 400 is a severe oil burner. If it did not burn oil though, I think i would stick with BP6es - these are fine on my dino with no fouling.

I think 412's have the smaller 12mm thread like a 328, but 400i are 14x1.25, which is totally std.

FWIW, try BP6EY, instead of ES. Same price and cleaner spark with V groove.

 

Some other people I know have given up on Champion plugs in Ferraris. My GTC had N7Ys in it and I could rarely get more than around 2000 miles before they would misfire and load up.

When I started using the NGKs, I was amazed at how much longer they lasted.
The BP7ES were fine for hard high speed driving but for all around driving the BP6ES was much better. After the GTC turned over around 130,000 miles, the oil consumption was getting worse and I switched to the BP5ES.

Here's another thing that's great for Ferraris, especially the older ones - remove the Marelli coils and ballast resistors and substitute the Bosche Blue ignition coil - as far as I'm concerned, it's the best product of its kind on the market.

Back to Champion plugs - I use them exclusively in my aircraft and have NEVER had a problem. They seem to be the best thing available for aviation applications.
