Ive already read the dozens of dozens of posts about 'which gap is mine?' and this isnt the problem.

.044 ls etc
.052 gsr
.044 type r

First shop gives me entirely wrong plugs. Autozone gave me laser platinums but for an accord according to NGK's site and the number on the box. However theyre .044 gapped as well. I didnt notice the different numbers until i installed them in my GSR but the car is running and feels better then my used plugs. I dont know if autozone will take them back since ive used them but ill try if i have to. What are the adverse effects of running a different gap?

 

bump, cmon...

 

where are the techs?

 

.044" is good for higher CR motors, but you won't have a significant negative effect if you do run them at .044" Maybe lose 1 hp, if that.

 

That makes sense to me considering a type r is using .044 like the ls. Wonder why they chose to run a longer length on a gsr. So you dont think i should bother getting the .052 gap plugs?

 

If they are the wrong plugs take them back to AZ and exchange them for the correct ones then gap them to .052"

 

Just read this on wikipedia regarding gap. I guess this is why it'll work but isnt the optimum for the application. Either way i think ill get the right set and wait for the engine to cool down before swapping and returning the incorrect ones. First ill need to make sure theyll take back the ones currently in the car. Thanks for your help!

"As a plug ages, and the metal of both the tip and hook erode, the gap will tend to widen; therefore experienced mechanics often set the gap on new plugs at the engine manufacturer's minimum recommended gap, rather than in the center of the specified acceptable range, to ensure longer life between plug changes. On the other hand, since a larger gap gives a "hotter" or "fatter" spark and more reliable ignition of the fuel-air mixture, and since a new plug with sharp edges on the center electrode will spark more reliably than an older, eroded plug, experienced mechanics also realize that the maximum gap specified by the engine manufacturer is the largest which will spark reliably even with old plugs and will in fact be a bit narrower than necessary to ensure sparking with new plugs; therefore, it is possible to set the plugs to an extremely wide gap for more reliable ignition in high performance applications, at the cost of having to replace or re-gap the plugs much more frequently, as soon as the tip begins to erode"
