I use copper/nickel spark plugs in my Soarer (Sc 400). Cheapest available. Runs great!

The 1UZFE EGR Delete Kit is available for sale here.

I am using BKR6E-11 NGK spark plugs in my 1uzfe (1991 UZZ31 JDM Soarer).
They claim to last 25,000 miles.

I feel the car performs better than with iridium and double platinum plugs.

Anyone that needs a plug change might want to check these out.

It should also be noted that race cars use copper/nickel plugs for best performance, as longevity is not an issue.

What's your opinion?
