Ruthenium plugs, who here has use them?

[TyphoonFiST]

I'm considering picking these up once whoosh has em in stock. Any idea what difference the slightly smaller gap makes?

Ideally the gap should be closed with how many pounds of boost you are running. .026-.028 for a Stock FiST with a OTS tune is just fine.

Ruthenium show better burn and life than nickel(copper), iridium, as well as laser platinum.

Saw no difference between the Ruthenium and Iridium plugs...FYI

Gapped same as iridium and my idle smoothed out immensely. Or I before I changed the plugs I just forgot to have coffee and the no caffeine jitters made the idle feel rough...lol. In other words... Coffee...., It aint just for breakfast. It's possibly for fixing rough idle as well.

If I hear more good things about the silver coated electrode, Brisk 'wild and crazy guy' Czech plugs, I will try them next.

they are less expensive so if you see no difference then they are as good for less...but testing shows they are better

just installed these 1 step colder and car started right up and drove smoother than before. old plugs had 9k on them and were overly black imo....stock tune is too rich seems like.

Although my plugs had less miles on them, That is exactly my scenario. What did you set the gap at?

 

[SerialBrain2]

0.028 and the factory ones were exactly at that as well. I checked each one.

Pulled a set today that had 12,000 miles on them. I had gapped them at .026” originally and was not able to measure any appreciable gap erosion.

12,000 miles later a .027” feeler would not pass through the gap. Putting a new set in and I will run them for longer. Seem like good plugs.

Are you on stock Turbo? If yes....thats a waste of spark plugs. Those things should last alot longer as they aren't being abused as bad with Tuned and upgraded Turbo.

Nothing crazy- just a Whoosh hybrid turbo and related bolt on goodness.

I just changed to NGK Ruthenium 1 step colder plugs today(LTR7BHX). They came gapped at .027-.028", which is weird because on the ngk website it says they come gapped at .043". I was surprised to see my 1 step colder ngk iridiums had a gap erosion from .025" to .035". They've been on the car for approximately 30,000 kms or 18,641 miles. I'm on stock turbo, and just have bolt ons and a couple tune revisions done.

Just made the change from OEM to Ruthenium... stock ones had 80,000 KMs on them. Difference is noticeable, really smooth idle. Ready for Dizzy Custom tune!

I'm trying out the Brisk Racing Silver plugs, so far they seem good. I had 20k miles on my ruthenium plugs and they all kept the .028 gap except for one it came out at .026...I was E30 tuned but now I'm e-40 tuned on stock turbo with 7lb turbosmart wastegate. Comparing the Ruthenium to the Brisk Racing Silver I don't feel any initial difference but I will give an update later when I put some miles on them.

Haven't been able to find anything concretely definitive, but I believe the OEM "CYFS-13Y-RC" spark plugs are 100,000 mile platinum. A part number decoder (like what we can find with NGK) might help. Platinum has the highest resistance, but longest lasting. Copper is the lowest resistance, but wears out quickly. Iridium is somewhere between the two... lower resistance than platinum, but doesn't last as long.

This is incorrect * Iridium and platimun are about the Same for longevity/ service life* I've seen anywhere between 50k and 100k depending on manufacturer.

This is likely only due to there being Platinum-Iridium hybrids.

Totally incorrect not sure where you got that information from but Platinum plugs do not last longer than Iridium.

What about iridium spark plugs?

Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
