Spark plug mod
 

I've had some really good number on my last tank(considering it was mostly city) and lately on my commute.:) The only thing different besides removing the WAI (which was for about 100 miles) is a spark plug mod found here.https://fueleconomytips.com/index.php...id=31&Itemid=2
I just used the standard NGK plugs regapped at .035 instead of .044 and indexed. These plugs replace the side gapped and index one that were in there. I've got about 350 miles on them. Don't really know how to test this but it sure is not hurting anything and only took about 35 minutes to.

so wait, all you did was get off the shelf plugs and close the gap?

No you drill a 1/16" hole in the bonding strap above the electrode and then dish the electrode a little so that when it fires the spark will go through the hole in the bonding strap for more spark front. There's pictures in the link. It an interesting idea, granted that there is only 2-3% to be gained in this area but every bit helps.

I'm planning on doing extensive plug testing somewhere down the road, it'll be expensive, but whatev, it'll be nice to know also, I say, so yeah.

Anyone know who has the indexing washers now?

I still have them. Just tell me where to send them.

I guess you dun got my address no mores. I'll pm you with your fancy instant messaging client.

Got your address via gassavers IM! I know... I am living on the edge.:p

Will send them out tomorrow. Still waiting for my MID and ECU chips? Should I IM you my address?

Yeah, I guess you should, I lost it in the swap of sites and the whole falling asleep instead of burning you a new chip, :p

I'll cut your advance in half, just for kicks, shouldn't ping then, but what do I know, I'm pretty worthless.

Spark Plus Socket Size
 

My 2005 Prius mileage had been as high as 61.3 mpg for a tank of gas over the summer. In the past month, my gas mileage dropped to 57.5 mpg, and the Prius, on occasion, wanted to stall when I accelerated or decelerated - although it never actually did.

I bought a set of Autolite platinum spark plugs to see if maybe the plugs are fouling. Can someone tell my what size spark plug socket I need to use to get the spark plugs out?

Why not use plugs with open electrodes.

I have used Magneti Marelli 4 electrode splugs extensively in performance applications.

Or you can use these..

But I have not seen an ounce of FE improvement.
