MSP owners manual "addendum" states a gap of 0.7 - 0.8 mm (0.028 - 0.031 in.) Also....always check the gap before installing...even if they are stated to be pre-gapped. Some plugs come pre-gapped way different than your required specs.

here's an idea of some of the gaps that come on the Plugs: http://www.sparkplugs.com/search_char.asp?threadSize=14mm&hexSize=5%2F8%22%2816mm%29&gap=&seatType=gasket&terminalType=&heatRange=&reach=19mm%283%2F4%22%29&resistor=yes&manufacturerID=1&action.x=64&action.y=14

wow there seems to be alot of mixed opinions on the correct gap!!

 

[hi-perf]

hmm FP-DE vs FS-DET

different engines and valve covers so i guess i shouldnt have chimed in.

i have heard from mp3 ppl that .038" was their correct ones.

I'm hoping that those that put "0.35" and such meant to put "0.035"...That's one hell of a difference. And I understand the typo thing, I'm not being anal, but that is significant, and someone who doesn't know better would have thier gaps screwed all to hell (whether they gapped in mm or in.).

[mspeed101]

so is .035 the correct gap then for mazdaspeeds?

I'd like to see the gap tool that reads .35!

I was working on my car all weekend and I purchased NGK Iridium Plugs and they were gapped at .044 out the box. And the parts guy told me that they were pre-gapped from factory! Well after installing them on my car, the car was runing pretty bad let me say. I re-gapped them to about .035 and the car runs way better now, it was bogging down before while accelerating through first, second and third gear, but not anymore!! I guess I should take them down to .030? What do you guys think?

Thanks guys.

Boosted cars run better with a narrower gap. Less chance for misfire. .030 - .032 for stock. .028 for higher boost. I posted about this topic way back when, search for it.

i bought the NGK BKR7E plugs from apex, they havent come in yet but are they already pre gapped to fit the msp? or do i have to gap them?
