I was wondering about using NGK iridium in my "90. ?? I really like these plugs and have used them where ever I can.

I use AC 41-602 plugs. They seem to work fine and they are inexpensive enough that I can change them out every year or two depending upon how many miles I put on the Z.

For my 91' NGK Iridium BKR5EIX Eagle
Gapped .043".
I will use anti-sieze on stainless steel bolts, spark plugs, and header bolts (Permatex Anti-Sieze 133A).

I sent a message to Marc Haibeck since I plan on changing mine this winter. I'm sure he wouldn't mind if I share his response ...

The 41-602's are very good. I gap them at .035". They are inexpensive and last about 15,000 miles.

The best plug is the 41-801. It's a double platinum with a smaller pointy electrode. The smaller electrode has a better electric field for a .045" gap that might contribute to a better idle. They are expensive at about $70 a set but they will last about 50,000 miles.

I already have a few sets of the 41-602's, but decided after reading this, why not pick up a set of the 41-801's. Went on ebay and found some very inexpensive compared to what was mentioned in the text.
When I spoke to the PO before the previous PO, he informed me that he changed out the plugs at 55,000 miles. I am now at 68,800 miles, so I will probably change them out this year......

The mail in rebate for all Delco plugs is in effect for all of 2017.
41-801 the double Platinums are $5.20 a hole, so the $2.00 rebate brings that down to $3.20 a hole.

Iridiums are discounted $3 per plug
Double Platinums $2.00
Rapidfire Performance Single Platinum ($1 per plug)
Professional Conventional ($.50 per plug)

The 41-602's are $1.44 or $0.944 a plug after the rebate.

I just bought six 41-834 plugs for my Atlas Inline 6 cylinder, and they were $10.00 a piece. Not cheap but they cover GM's 100,000 mile warranties these days.

The OP was asking about E3s. They are crap. Don't waste your money.

If budget is tight, consider the above mentioned ACDelco discount/promo price.

If you want really good spark plugs and are not too concerned about price, for the last 15 years I owned Barney, my 500-hp '95, I used the Denso IT-22 (two sets) exclusively. Great performing plug with pretty darn good plug life. I also use the IT-22 in my LS6 and LS7 engines.

Found out from Yun that the plugs that I had ordered AC-602 and have and the most recent ones ordered AC 41-801 are the incorrect spark plug type for my 94. Learn something new all of the time. These are all brand new and in the box. I will sell them for a good price plus free shipping if anyone is interested and will also list in the
FS section....

Ordered NGK 7397 Iridium IX TR5IX which are the correct for the 93-95 ZR-1's.
found them for a decent price and local on ebay.....
