Running e85
80lb injectors
3bar FPR
A tune
K27/8

Plugs are ordered from 1-4 cylinders

Do you guys think these look correct?

look a bit lean but these pictures can be difficult to read. Do you have an afr gauge?

Just bought 1 and will be installing it this week.

I read that e85 will make them white like plugs 1 and 4.

Do you agree?

Tips look great! No. 2 looks a little oil soaked. Are you consuming any oil? Wb afr is a great idea. What brand did you buy? Mike

Mike, I am consuming oil at about 1 qt/750 miles. Mechanic said none of the plugs looked oily. Compression was high 130's across all cylinders at sea level.

I purchased an Innovate LC-1 wide band.

Thank you for your input.

Seeing that I installed the 80lb injectors about 2000 miles ago when I switched to e85, do you think maybe the injectors need to be cleaned from all the crap that alcohol releases?

From what I've seen, the notorious E85 injector gunk is more likely to build up if you installed new fuel lines since using E85. It's not hard to pull the injectors and check them directly.

Paulyy

alcohol is a cleaning agent too. the gunk is from the fuel tank from what ever you where running previously. That is usually at the bottom of the fuel tank. The fuel filter is there to catch the gunk and other particles that aren't fuel. When first running e85, it's recommended you replace he fuel filter after so many fill ups.

E85 will, a lot of times, leave a little bit of whitish residue.
The car might be a little lean - adjust the FQS to add some fuel.
It looks like your cylinder #2, and a little on #3, probably has a worn intake valve guide/seal. Which is pulling in, and burning a bit of oil.

What is everyone's thoughts on running the NGK 7 (one range colder than stock) with E85 ? I ran the colder plug with gas but went back to stock range when I switched to E85.. what say ye ??

lart951

they dont make the bpr7's do they?

Rogue_Ant

That is what I suggest for a track car.
A street car, the stock heat range will probably have a little nicer idle and low-load.

BPR7ES? Yep, stock number 5534.

Joshua, So you are saying the 7's are correct for a street car running e85, correct?

Rogue_Ant

7's are fine for a street car, and are a factory-fill heat-range for a lot of cars.
