Are ngk pre gapped

[A4SANDBEER]

Ordered ignition kit from pure motor sports so maybe they can answer
I have 2.0
Are the spark plugs pre gapped

[A4SANDBEER]

Never mind I called pure and asked , they are pre gapped

I don't know why I posted this stupid thread lol

Have a nice day people

[Audibot]

All the ones I have gotten have been gapped appropriately, but I always check them prior to install.

+1 You should still check.

[Biged243]

+2 check

[PNW Avant]

The number at the end of the part number corresponds to gap i believe.

Its so cheap just buy it and gap to 0.028 and call it a day

Keep in mind spark plugs can be used for other cars and may not always be pre-gapped for your automobile. Or some factory worker came in drink and gapped then wrong. It happens.

[B7AudiSline]

I have always checked the gap on every spark plug I have installed, takes a few seconds for peace of mind.

[Biged243]

I love playing with gaps



<**-Loves gap.....

Enuff for /thread

[Samsonite]

hmmm, wonder which is the best size gap for me?

[Biged243]

Ummm......... My answer for you would be yes.

[mcbuck]

always check, I have occasionally found ngk out of spec by a couple thousands.

now as far as the best gap .......... it's like the story of the 2 bulls standing on the hill looking at all the heifers below them. the young bull says "I'm going to run down there and screw one of those cows." the old wise bull says "hold on son, why don't we walk down there and screw them all?"

[Biged243]

Nice analogy, I like it.

[Samsonite]

Haha good answer sirs

[konarider94]

Because we are talking about spark plug gap many people don't know the proper way to gap the iridium and platinum plugs. Don't use the disc style tool because you can break the tip off the plug.

For reference, the NGK BKR8EIX's I just got were all pre-gapped at 0.030.

I've read on here that anywhere from 0.028 - 0.032 is acceptable, I gapped at 0.029 and called it a day. My old (copper) NGK plugs had worn down from 0.029 --> 0.033 over the course of 9k miles

[Sanjman]

If you don't know what you want to set your gap at, then use 0.028 or 0.030... don't go to go 0.032 unless you are confident in your decision and why you're doing it for you car setup. Don't create issues like misfires, we see new threads about it all the time and the first thing pops up is what plugs and what gap you're set at.

Edit: Removing misinformation

[konarider94]

Did you even watch the video? Don't set your gap by cramming shit in there. The feeler is just to measure. Use the tool to bend the ground electrode if you need to.

[Sanjman]

I didn't at first because I couldn't at work... just watched it and you're right.

Wow you got 9k out of them that is a lot for copper. I only get about 5k before I start misfiring on wot, which is fine because I change my oil around then too.

I hadn't planned on going 9k, but didn't notice any misfiring and honestly just forgot about it. I was completely stock at the time as well.

I flashed the JHM tune and installed new coil-packs along with the new BKR8's, so we'll see how they hold up.

[Charles.waite]

I've run a .044" gap in the past.

<------This guy is CRAZY!

[Biged243]

You are crazy, on stock coils?

[mr larry]

I used to run .044" too with the red coils. Honestly I never could tell any difference, no misfires. The biggest change I ever noticed was switching to copper. Night and day better.

[Charles.waite]

You are crazy, on stock coils?

Latest 07k revision F coils. I swapped back to OEM bosch plugs in August when I was selling my car. Honestly, I couldn't tell much of a difference. I just didn't want to sell a car with a non standard setup and plugs are cheap.

Didn't sell the car but I kept the bosch plugs since I put the BKR7EIX-11 plugs into my b6. Which, by the way, I've run a .044" gap on with the same coils for about 3 years now. In the b6 it noticeably smoothed out the idle and power delivery.

Do you have results for the B7?

[Jake@JHM]

don't run a .044 gap. It will work on a stock tune with stock boost levels, but it is not recommended because it makes your coil packs work harder.

On a car with increased boost levels like with a tune, you will start misfiring under load with a gap that large and you can kill a coil pack pretty quickly like that.

Gap should be .028 for this car. If you are boosting over 25psi I would recommend dropping the gap to .025. This is because with more boost there is more cylinder pressure making it harder for the spark to jump the gap. Closing the gap will help the spark jump. Going too small of a gap will also misfire because the spark isn't their long enough to fully ignite the fuel.

This.

Wasn't intending to mislead anyone here, but I wouldn't recommend it on anything but a stock car. The 2.0t is a pretty high compression engine and too big a gap will easily cause some misfires.

I ran that large gap on both my b7s at various times, but they were both totally stock. I currently run it on my b6 but its a 1.8t with lower compression.

As far as results, what do you mean? I noticed marginally smoother running but that was probably because I installed new plugs and the old ones were super old, not because of the large gap.

[Audibot]

Gotcha. Jake is there a linear relation from a gap of .028 to .026 as one trends higher in boost? I see peaks of 23 psi every once in a while, and can reach 21 pretty consistently.
