Is there anyone using these iridium plugs in a 5.7 Vortec? I heard they only do well with platinum plugs, and run cranky with iridium & others.

The plug show here, ACDelco 41-993 is not an Iridium plug, The description is incorrect, they are Platinum.

I have theses since last year Xmas in my Suburban absolutely no issues at all

These plugs have been in my 99 Tahoe with the 5.7 Vortec for over a year and they perform noticeably better than the previous set of Bosch platinums.

I have used theses plugs many times and have always had great service from them

These plugs are no better, and I believe a little worse than the OEM choice. Iridium sounds great, but I tuned up my 5.7 with wires and the other components, and it will not run quite as smoothly. Just my opinion.

This thing is great...a bit pricey....but well worth it IMO. Can't answer specifically about your 5.7 eng. but it is generic enough that it works on a great many motors. I don't see a lot of suitable options other than an outrageously priced SST from the dealer. Good luck.

just as the other cust. said there no need to set the timing on your engine this ig. box dose that yust perfect, i aso purc. that msd wire harness for this ig. box it hooks up in perfect to this box.also paired this set up with a new msd billit dis. mod. 85551 and a new coil with mounting bracket mod. # 8313 and coil # is 8202 hope this with your new project to come dan p.

The gap is preset on iridium plugs. Do not try to adjust or gap these as you will damage the tip of the plug. I believe the gap is set at .060" but as I said please do not gap these. I learned the hard way.

I would just check and see if plug ultima recemmneds crosses over to this. That's all I did for my engine as Bosch are oem plug. Sorry can't help you more. If no luck I'd see what other engine makers are using based on that size of v twin engine. That may help some.

the r44ts is a copper resistor plug, the 41-993 is a iridium tipped plug that is already pre-gapped for a high energy ignition, what is the year and make of your vehicle? i do not believe these two are compatible based on this information, plus i believe the r44ts is a thicker diameter plug.

hey rosems...looks liquid cooled so your going to want to actually go to the trail tech home page and look for the universal fit kit that matches your machine's parameters, and just fugue for some degree of custom mod to the speed-o pickup....the differences in the Vapor kits are all in the included types of sensors that intemperate the machine to the digital dashboard common to all Vapor kits....so your looking at the wrong kit for your application, but i am certain there is one...i am not, however going to tell you which one it is or i am going to be expected to do that for everyone, and i don't work for trail tech, so that's not my job.... rulgert

Those threaded sensors were the upstream o2 sensors on my 4.7 tundra v8.. the downstream sensors had a bolt on each side to secure it. At least that was the case for my application.

For uses with platinum plugs these are great plugs but I think your car needs copper. It may change your performance in the wrong way

I'm satisfied that the Iridium plugs are working well in My 2005 Dodge Hemi... Not sure a Chevette needs them but it can't hurt I guess.........

Not good to use different brands front and rear. I'd look to see if the IRC wild flares WF920HD has sizes to fit. I use them on my Kawasaki 1500 Classic and got great mileage from them. I run the Commander II on my Vulcan Voyager but I don't use the stock size.

I use them in the innokin itaste svd and they work great. I don't know what a mech mod is.

The Iridium plugs are supposed to be factory gapped, you might want to check them but you really don't want to be gapping the iridium tipped plugs. I ordered a 4 pack and all were fine. Also, get a long enough extension for your ratchet, the long tube entry to put them in is kind of a help as the spark plug socket will slide in the port and guide the plug right into the thread, helps keep from fouling the iridium tips on the way in.

I believe all of the Vortex Dot sites are compatible, and the Sparc II with it's multi-mount system is definitely. Anything with absolute or 1/3 co-witness will work.

I actually returned mine, the connector did not fit my helo. If i remember correctly it was 5.2 vdc

I put mine in a 00 Camaro Z28, rear, and the cruise control stopped working, not enough resistance, the ECM thought bulbs were burned out as my research found. Had to add the resistors to fix that problem, so Id recommend spending the extra few bucks and getting resistors (one for each bulb) to save you time later. Didn't have any issues with the actual blinking or relay though. I also have them as DRLs in my 03 Avalanche, nice and bright, work great.50W 6Ohm LED Load Resistors for LED Turn Signal Lights or LED License Plate Lights (Fix Hyper Flash, Warning Cancellor) I put mine in a 00 Camaro Z28, rear, and the cruise control stopped working, not enough resistance, the ECM thought bulbs were burned out as my research found.

Best thing for you would be to contact Pulstar through their webpage. I had to do that to find the right plug for my Victory XCT.
