*

About 30K ago I placed in a fresh collection of Denso iridium plugs, Toyota dealer claimed thew were already gaped, I"m walking on a lengthy trip and also thought i should inspect my plugs and also maybe re gap them...Plugs were good but check the gaps all were .038 and the void was provided at .044, I adjusted them come the correct gap at .044 and also the car seems to idles a tiny rougher(or mine imagination) was I best in transforming the gaps to the right space specs or have to I just have left them at .038...Would the gap difference have effected my gas millage?BTW an initial time i cleaned my throttle body in 160K yesterday,.. Traction it completely off and it was nearly like new, just a little grime...

it is ok to gap iridium plugs if they are not to spec, it just depends on which kind of gapping tool you use. Do NOT usage the one that is a disc with a "ramp" going approximately the edge together this kind can break off the iridium reminder of the plug.

It sounds like your tool might have to be innacurrate. Borrow another one or lug it come a shop and also have castle verify the your tool is correct.It is true that you room not claimed to gap iridium plugs, at all, ever. I wonder if the metal can"t stand up to the stress of taking devices to them.Did girlfriend disconnect the battery while instead of the plugs? If friend did, then her ECU more than likely reset and your automobile hasn"t readjusted yet. Friend would definitely have unstable idle problems after resetting the ECU if your throttle human body is dirty (common top top this car).
Was friend spark plug gapper do in China? I have one do in the USA and one in China and they both read various gaps top top the exact same plug.
Was you spark plug gapper do in China? I have actually one made in the USA and also 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 do in the USA, and also I never had a problem with it. That wasn"t a faulty gapper it was the faulty gap collection from the manufacturer or could have to be banged increase in the shipment to Toyota, countless reasons the it could have happened. Mine mistake was trusting the pre-set gap and not checking them myself prior to I put them in....Like i said once I pulled the plugs they all were gaped at .038 not .044 together spec....Enough said...Thanks all...My cars back to running fine!

Good think your auto runs good.The only thing I have actually left come say is that I find it unlikely all 4 plugs occurred to all be banged up in shipping resulting in the specific same incorrect gap throughout the board.

Did you get Denso SK16R11 or IK16 spark plugs, which are claimed to it is in pre-gapped come 1.1mm (0.433")? I mean you did... It is strange the they were all gapped to 0.038". They were more than likely not effectively gapped at the Denso factory... Some other Denso spark plug models perform come pre-gapped come 0.9mm (0.354").
Did you obtain Denso SK16R11 or IK16 spark plugs, which are an alleged to be pre-gapped to 1.1mm (0.433")? I expect you did... The is strange the they were every gapped to 0.038". Lock were probably not appropriately gapped in ~ 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) with platinum coated floor electrode.You can upgrade come Denso Iridium power IK16 (φ 0.4 mm iridium alloy center electrode) with taper-cut U-groove floor electrode, or Denso Iridium tough VK16 (φ 0.4 mm iridium alloy center electrode) with platinum tipped soil electrode... They"re every (supposed come be) pre-gapped come 1.1 mm (0.0433"), as required.

I walk that and also now I"m changing out the plugs. Ns bought a kind wire form gauge. I think I used that facility electrode as a bar (with a wedge kind gapper) come make certain the space was perfect. Woops.
If you got the -11 plugs lock should currently be gapped to 1.1mm. I do regap share ones an extremely carefully. Never a problem. I’d be surprised by how much off your -11 plugs were, yet then ns don’t usage Densos and don’t plan to. Just NGK ignition products. IMO the best there is.
it is ok to void iridium plugs if they are not come spec, it just depends top top which form of gapping device you use. Do NOT use the one the is a disc with a "ramp" going approximately the edge together this type can break turn off the iridium tip of the plug.
