*

About 30K back I put in a fresh set of Denso iridium plugs, Toyota dealer said thew were currently gaped, I"m walking on a long trip and also thought ns should inspect my plugs and also maybe re void them...Plugs were good but check the gaps every were .038 and the space was noted at .044, I changed them come the correct gap at .044 and also the car seems to idles a small rougher(or mine imagination) to be I best in changing the gaps come the right void specs or must I just have actually left them in ~ .038...Would the gap distinction have effected my gas millage?BTW very first time ns cleaned my throttle body in 160K yesterday,.. Pulled it totally off and also it was almost like new, just a tiny grime...

it is ok to void iridium plugs if they room not come spec, it simply depends ~ above which form of gapping device you use. Execute NOT usage the one the is a disc with a "ramp" going around the edge as this type can break off the iridium pointer of the plug.

It sounds favor your tool could have to be innacurrate. Borrow another one or bring it come a shop and also have them verify that your tool is correct.It is true the you are not supposed to void iridium plugs, at all, ever. Ns wonder if the steel can"t withstand the tension of taking devices to them.Did girlfriend disconnect the battery while instead of the plugs? If friend did, then your ECU probably reset and also your automobile hasn"t readjusted yet. Girlfriend would definitely have rough idle difficulties after resetting the ECU if her throttle body is dirty (common top top this car).
Was girlfriend spark plug gapper do in China? I have one make in the USA and also one in China and they both read various gaps ~ above the exact same plug.
Was you spark plug gapper make in China? I have actually one made in the USA and one in China and they both read various gaps on the very same plug.
I have actually a premium Lisle spark plug gapper & feeler gauge set and made in the USA, and I never had a difficulty with it. That wasn"t a faulty gapper it to be the faulty gap collection from the manufacturer or could have to be banged up in the distribution to Toyota, many reasons that it might have happened. Mine mistake to be trusting the pre-set gap and also not check them myself before I put them in....Like ns said once I traction the plugs they all were gaped at .038 no .044 together spec....Enough said...Thanks all...My cars earlier to to run fine!

Good think your automobile runs good.The just thing I have left come say is the I find it unlikely every 4 plugs happened to every be banged increase in shipping resulting in the exact same incorrect gap across the board.

Did you acquire Denso SK16R11 or IK16 spark plugs, i beg your pardon are claimed to it is in pre-gapped come 1.1mm (0.433")? I mean you did... The is strange that they were every gapped to 0.038". Lock were more than likely not properly gapped at the Denso factory... Some various other Denso spark plug models carry out come pre-gapped to 0.9mm (0.354").

Original typical plugs space Denso"s Iridium Long-Life SK16R11 (φ 0.7 mm iridium alloy center electrode) through platinum coated soil electrode.You can upgrade come Denso Iridium power IK16 (φ 0.4 mm iridium alloy facility electrode) with taper-cut U-groove soil electrode, or Denso Iridium challenging VK16 (φ 0.4 mm iridium alloy facility electrode) with platinum tipped soil electrode... They"re every (supposed to be) pre-gapped come 1.1 mm (0.0433"), together required.

I did that and now I"m transforming out the plugs. Ns bought a decent wire kind gauge. Ns think I offered that facility electrode together a lever (with a wedge form gapper) to make sure the void was perfect. Woops.
If you got the -11 plugs lock should already be gapped come 1.1mm. I execute regap share ones very carefully. Never a problem. I’d be surprised through how much off her -11 plugs were, yet then i don’t usage Densos and don’t plan to. Just NGK ignition products. IMO the best there is.
it is yes sir to void iridium plugs if they are not to spec, it simply depends on which kind of gapping device you use. Do NOT usage the one that is a disc v a "ramp" going approximately the edge as this type can break off the iridium pointer of the plug.
