Cheap spark plugs for ca18det?

[dhen]

Hi,

Do you have to use iridium plugs on the CA? I don't mind spending money on something like a turbo, but $60 seems like a lot of money for a set of spark plugs.

Anyone know of a set of copper ones that work? Will they foul out?

Thanks,

Darian

$60 is a WASTE of money on spark plugs. Get yourself some BCPR7ES plugs for $7 and call it a day. Not only are they cheap, but if your car happens to detonate, you have a better chance of blowing off the electrode than destroying a piston.

I asked for those plugs and they didn't have them in stock. They did have some Champion ones that they cross referenced. We'll see how that goes...

Thanks,

See if they have the BCP7ES (not the "R" in it). Same plug, just doesn't have the Resistor to cancel electrical noise.

I already installed the Champions, but thanks for the info if these don't work out.

I would NEVER run anything but coppers. My CA loves them.

I've got iridium's, but the coppers work great. The only real advantage of the iridium's is that they have VERY long service interval and are less prone to fouling. At the time that I purchased them I wasn't running E85 yet and was having to throw a lot of fuel at the motor to keep it from detonating.

When these iridium's wear out, I'll get another set of coppers again.

Where did you find iridium plugs for $60?!? I got my set of BCPR6EIX-11s at O'Reilly for $26 for the set. That is nuts.

i would pull those champion out, and run denso or ngk.

autolite AP3924 or AP3923

[elmpomp2]

really?

ive always been told to avoid autolites, no personal experience though.

i always use ngk or denso and have never had a problem.

i have had personal experience with bosch giving trouble though, avoid them.

[themadscientist]

I had good results with Autolites. They were not as tough as NGKs but not junk. Bosch, now I can confirm they are junk. I had nothing but trouble with their platinums.

Ive had problems with Autolite plugs. My best ones to date (cost-wise) were either my Denso NGK substitutes ($3 for 4) and my Motorcraft (yay ford!) ($2 for 4). Those Motorcraft plugs got me through good and bad times, and lasted about 25k miles. Awesome!

Search http://www.ngk.com for 1995 Saab 900 turbo plugs...they are the same as the CA18DET.

I thought I'd give an update on my plug search.

I bought a set of cheap NGK plugs for 95 Saab 900 turbo. They run fine, but they're too hot:



They came gapped at .042 inch. Can I just reduce the gap, or should I get different plugs? I'm not asking because I'm cheap, I'm trying to find a good plug to use for when I need replacements, etc.

For those who are following this thread, these plugs didn't work well:

AC Delco 41-602 - gapped at .6 and then .8 mm. NGK IFR7G - you'd think these would work. I got them from a shop that didn't know what they were doing. I say that because these also didn't work.

Do you have a part number? These sound good.
