I've been wondering this too... How important is it that I change to spark plugs more ideal for a FI application? I was under the impression it really didn't matter.

copper plugs or Iridium plugs

pimp my yaris · 12-01-2010, 05:34 PM

I just installed some NGK BKR7E plugs. They did not have the iridium BKR7EIX in stock and they were 10$ each. I will see how these work.

PETERPOOP · 12-01-2010, 08:34 PM

What gap did you set?

pimp my yaris · 12-02-2010, 01:15 AM

Unfortunatly I could not find my plug gapper, so I installed strait out of package after looking them over.

pimp my yaris · 12-24-2010, 02:21 AM

For a long time I have had a occasional missfire under heavy load or full accel. I removed the spark plugs I installed previously and closed the gap to about half. I wanted to see if the smaller gap would lessen the load on the ignition coils, and it worked. No more missfire. It would cause a big jerk when it happened. Im sure the correct fix would be a stronger ignition system, but no flow for that now. Its nice when the car feels reliable like oem just with more power.

I'm glad it worked, but I suggest you gap those with a tool when you have a chance.

yeppers, i gapped my ngk vpower plugs at .22, i had that same problem. boost was blowing out my spark at full boost. was getting a jerk and misfire under hard acceleration. FYI, this was on my crx with 10psi, not my yaris

Focus_Sh1ft · 12-25-2010, 11:34 PM

AWESOME. This is just the information I was looking for. Recently I've been having the same problem but it has become more noticable. I always thought it was the transmission jerking because it always happens shortly after a shift into 3rd(?), but this sounds more likely. The sudden loss in power is a huge buzz kill.

I'm gonna swap my plugs. Recommendations? Thinking I'm going to get the same plugs if those are the one's that are a step colder than stock.

ilikerice · 12-26-2010, 03:00 PM

i used vpower ngk for all my honda engines. personal preference, but hope one of these other toyota boosted guys will share thier thoughts on plug preferences.

I use Denso IK22 Iridium Tough Power. They are one step colder than stock.

NGK's should be used on any asian brand car. Nippon Denso's can be used if NGK is not available. And no matter what dont ever use Bosch. You will have nothing but headaches and missfire problems. And Champions are only for lawn mowers and chryslers.

I've had bosch platinum 4's in my car for 30 000 km now with no problems. But on the other hand I'll be going back to NGK or Denso when these are done. the price isn't worth it.

This is a very interesting post, I spent almost 3.5hrs to finish the whole thread.

What the total you spent so far?

I wish I can build a nice and budget turbo like you did. Too bad it can't be happen until I buy-back my leasing Yaris (1 more Year from now)

Hopefully you guys will have a perfect tuning with FIC by that time.....

pimp my yaris · 01-10-2011, 10:16 PM

With piggy back and exhaust I would say about 2000 to 2200 bones
