sparkplugs
 

want to put new plugs and want to know what people use I had e3 in but have to replace them:flag:

Re: sparkplugs
 

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

Re: sparkplugs
 

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.

Re: sparkplugs
 

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.

Nice find.

Thanks :-D

Re: sparkplugs
 

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.

Re: sparkplugs
 

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.....
