MY 93 wrx import, full de cat

I've had my NGK platinums in for 1500 miles and
after inspection the plugs are coated in a red oxadised film.
I use optimax with millers and use as suggested.
used silcolene pro boost for 4 months before millers.

Is this normal? Don't want to cut back to much to avoid det probs.

With new plugs car is flying again- hope they last longer.

Anybody had similar probs? suggestions.

I have been using proBoost now for over a year, With Optimax & had no probs with plug fouling, Uprated fuel pump also

Lpg converted cars suffer with that

 

It is normal with octane booster.

 

This is normal apparently with millers,or at least that is what the sales rep told me at the time of buying a case.
I believe it is something to do with manganese but I could be wrong.

Its normal with virtualy all boosters "you've been tangoed" !!!

Can you not just sand off the red coating with emery cloth and re-gap the plugs if they have so few miles on them rather than buy new ones?

Nice to know, I run Wynns's booster and Optimax, think it is time I check my plugs to see.

 

The plugs came out at Pro Sport, they said they were goosed.

I should have taken them home to try to clean, Doh.

Would be interested to know if they can be cleaned and are
still ok?

I have to change mine every 3000 miles as the performance noticeably deteriorates after this.

(100ml NF per fillup)

You could clean them up I suppose, but be very careful especially with very fine tipped Iridiums. Don't go mad with a wire brush. If you damage them in the cleaning process, it could end in tears.

Problem with trying to clean them is debris drops down between the tip insulator and the metal outer body which can cause it to overheat. Cost versus effort of removing them I would be tempted just to replace with new ones.

 

So are we saying then that if you use OB then your plugs will only last 1500 miles or so? sounds expensive if you use hks plugs like me.

 

Bigger problem is that millers leaves a residue on Lambda probes

Not good

 

I have just started using Millers and the car runs so sweet but how long before my Lamdba sensor gives up?

 

Thats interesting.

Guess what I had to get 3 weks ago - yes a new
lambda sensor and as mine is an early 93, only one
fits - Cost £250
Tried the Halfords one - overfueled.

Scooby ECU here I come!!

hmm ive had my plugs in for just upto 12k miles (ngk jobbies)
and i use 75ml per fill up, although for the first 7 montyhs it was 50mm and 3 months back i was useing none as i turned the boost down

was planning to change mine yearly (due in march)
i used a halfords lambda no probs at all

 

My lambda sensor has done nearly 40,000 miles on booster and is still fine, shouldn't be a problem, halfords won't stand the temperatures for too long.
