Pregapped plugs aren't always correct. It's ALWAYS good to double check, as you did.
Make sure your sources are correct. I'm actually finding mixed answers on this site alone... ranging from .039 to .044 (many incorrectly shown as you have, as .39 or .44)
If it were me, I'd put them in as-is, and adjust them if the engine doesn't seem to run properly. That, or seek a better source of information, since it seems rather questionable on here...

0.44 is the gap. I think I saw it in a manual or check under your hood.Comment

These don't come pre gapped. I put them in a cd5 last week and had to gap them, and I bought them for my 2.0 and I have 2 gap them.

I've always ran mine at .42, never seemed to have any issues with them.Comment

The correct gap is 0.44 auto zone says so. Orielly says so and the manual. and also under the hood say so. I actually just did plugs and my car was running like crap. So I had to go through a headache getting all this simply but very useful information.Comment

Let's be a little realistic here. Its a lil hard to get it exactly at .042 using that round spark gapper. For me I actually put it at .045 if it goes further I do close it.
.045 seems easier to gap than being so accurat at .042 or.044**Blk Housed Slut Crew Member #1**

Just get the G power. $.60 more and you don't have to (can't) gap them. Problem solved.MRT
37.5 MPG, AC on, cruising at 80.
30.0 MPG, AC on, aggressively driving around 90.
27.5 MPG, no AC, cruising at 90 with occasional gridlock. 40 degrees Fahrenheit

0.44" is about the thickness of my little finger. I'm pretty sure that's not the right value.Originally posted by Bad_dude View PostComment

Or take 2 seconds to check and adjust the gap if needed. You can use shims to check more accurately than the round gapper.Comment

i look at them and throw them in. you're not going to see a difference on a stock motor.Comment

What part number did you use?Originally posted by F20A CB7 View Post
NGK's come pregapped, and the correct gap is 1.1mm
Hence the part number - ZFR5F-11
11 = 1.1mm

There must be one "0" before the first "4".
My Haynes manual says .039"to .043".
Decal under the hood of my car says 1.0 to 1.1 mm.
1.1 mm is equal to .04331".
1.0 mm is equal to .03937".
Anything below minimum, there may not be enough spark to promote good burn.
Anything above maximum, there may be over taxing the ignition system.Last edited by oyajicool; 03-13-2012, 08:28 AM.A&P-IAComment

Set it at .041" and you are within the limits.Originally posted by 10thAnnivCB7 View PostA&P-IAComment

If your car ran fine when you took the old ones out then check the gap on those and set the new ones to that gap.Comment
