Difference between good plugs and faulty plugs:

We have just re-tuned Simon's car ready for his round of 0-400m today. Couple of months back, the car had a misfire above 5000rpm where we reset trigger levels on the Vi-pec to dismiss the tune. This resulted in a 335hp run.

However, at the last Kwinana drags, he complained of a misfire up top again which only gave him a best time of 12.7s.

Yesterday, we put his car on the Dynapack for a retune. This time round, the car hit 330hp max. After about 3 runs, the car started misfiring again, dropping power to 308hp. We tried to reset voltages and dwells, as well as trigger levels, but there was no improvement.

We then proceeded to change the Ik22 plugs and new coil-packs. Problems solved!! You can see the coilpacks at our O2/Coilpack thread ( http://www.perth-wrx.com/vb/evolutio...l-packs-2.html. )

Below is how Roughstilin's car performs when it misfires:


Below is the result of today's tune and our tune is health-proven. Stock STi 2.0 engine is still mint, producing awesome power boosting at a max of 1.85 bar of boost after all the events he has been to.

Thank you for your support P.WRX. We now stock the most complete range of performance spark plugs for all your Subaru needs.

Warning: I have just pulled a set of NGK Iriway copies out of a Subaru. Thought they were the coilpacks causing the misfire and detonation.

These are selling for under $15 each locally. Will not mention names but please don't cheap out on the spark plugs. Saving couple T dollars in exchange for a damaged engine is not worth it.

Always ask for proof of manufacture.

Cheers,
