I was looking for Astra plugs at the two local parts places I use and got a hit only on the Autoline products, the 5224.

Well, that seemed odd, so I dug into the cross reference and it seems there are a LOT of options from all the brands for a lot of different vehicles. Some of these plugs the stores have, but don't list. Kind of wierd, not what I am used to.

So, does anyone have any suggestions for the Ecotec 1.8 VVT? I have the Autolite Ir ordered, but I suspect they are not the best. I suppose these are all different heat ranges..?

Wow, even sparkplugs.com agrees with you. Usually I can find any cross reference there.

Only the Autolites and the pulstars and e3's are spec'd for your vehicle. Don't use the E3's, i've had bad luck with misfiring, and fouling up within 40km.

The Autolite 5224 is the OEM equivalent.

Heres a list of approximate cross references for the 5224:

Champion RC12YC might work, as its close, but doesn't match the OEM specifications. Its odd, thats what Briggs OHV intek motors use.

I have used the Autolite Iridums and I liked them. I know some people believe certain plugs are better in certain engines. Myself never having a vehicle and not knowing anyone with the Ecotec 1.8 I do not have a recommendation. But I am surprised as well that only one plug came up.
 
It seems use extended tip spark plug, this is common for Japanese car sold in Asia but not in US.
So I think the best bet is
CHAMPION 9202
DENSO SKJ16CR-L11
NGK ZFR5FIX-11

Beside the extended projected tip, the other part need to be examined is whether the shroud length is also extended.
If yes, then the best option may be different from above.
However, even you can find the exact model for NGK and Denso, it may be very difficult to find it in the US

Actually those Autolite Iridium XP's are a great plug. I've used them in 3 friends vehicles so far with great results. I put them in a 2005 CTS, 2007 Equinox and a 2000 Trans Am.
 
The Autolite center electrode is not lasting as other Iridium plug, and a lot of time autolite heat range is about half-range hotter than NGK for the same range.
However the build quality is good and I guess the ceramic part is better than Champion that is easily cracked.
 
Denso make a strong plug. Used K20pru-11 in subaru with MUCH better performance than NGK. The NGK iR work well in my yaris - though I havent pulled them since gas quality is atrocious and they wont read correct anyhow. I typ dont like Pt plugs, I find std copper core Champs and bosch work well. Be careful with the champ if you have a 1mm+/- gap to get the #4 on the end of the part number(for 40mil) OTW you will get a narrow gap and the gnd electrode doesnt like being heeled back to make the 40mils gap - makes a sprk near the GND wire bend which is a high quench zone. (why do I give all my tune trick out for free?!)

Did you compare the DENSO with standard NGK (BKR6ES-11) or the NGK V-Power with split center electrode (BKR6EY-11/BKR6E-11) ?

NGK is about 1/3 range colder than Denso for the same range of plug.

I have found the US made NGK v-power to be 1/2 heat range hotter than the equivalent xxxES standard gap japan made NGK - and not good performers over champ or autolite.I always had excessive grnd strap erosion on std ngk with short service life v. a denso or other brand on mazda and subaru engines.

on what application did you see this effect, and how did you gauge the 1/3 heatrange differential?
 
Years ago, I worked for the Nippondenso warehouse distributor in St Louis. The Denso rep told our countermen to look up each vehicle application in the ND catalog rather than use cross references. Plugs that cross reference, he said, do not always match. I would suggest looking up your car in the ND catalog and using the plug recommended. My experience tells me that ND plugs are a very good choice.

Normally I observed on small Japanese engine, like Toyota, Suzuki, Honda. The 1/3 heat range is not exact but that normally that what I saw from the spark plug tip color for the same gap and plug range, eg. K20PR vs BKR6ES, IK20 vs BKR6EIX.

The V-Power has much better combustion compared than standard NGK, so it may show hotter, and ignition quality wise this is the one should be compared with standard DENSO (same split electrode, just one at ground the other at center electrode).
But I would agree that DENSO might have better response due to smaller split/U electrode on the ground side

I agree. They're very good value.
 
Imma chime back in after I get them installed. Car only has 4500 miles. oem plugs are plain....whatever, with a 30k change interval. It could be five years until it hits 30k, so I'll burn the $20 to see how upgraded plugs are.

Meanwhile, at 45k, I'm itching to clean the Accord pl;ugs and inspect them, since I used 2c oil in the gas since day one. The CRV plugs came out clean after 30k or so on 2c.
