spark plug replacement

[userbbc]

does the B7 DIY still basically apply to the B8?

http://www.audizine.com/forum/showthread.php/331619-DIY-Spark-Plugs-for-Dummies-update-for-B7-A4-s

[naemcivic]

Thanx for the post. I need to check my plugs here, I am running on the rich side here, the cold days are coming. I am already hearing my exhaust poping on deceleration.

[userbbc]

It was actually a question regarding whether the B7 DIY outlines the basic process for the B8. Coming on 35k miles on my end and would like to do the change myself.

[naemcivic]

It dosen't make much of a difference with our B8. Do you have access to a sparkplug socket? And remember to be gentle with the wires and clips connecting to the coil pack, they could be brittle, especially in cooler climate.

[userbbc]

Thanks for the warning. Figured it would be similar. Just didn't want to miss out on any nice to know tips specific to our b8's. Still have to find a torque wrench and a sparkplug socket. Only have the 1/2in drive torque wrench which i use for the wheels.

How many KM do they suggets spark plugs at? 90 or so?

[smedly]

anyone have pics of this diy? Those new E3 plugs are suppose to be great

which spark plugs do we use for the Audi?

Also, could we not use NGK Platinum/Iridium plugs?

[userbbc]

How many KM do they suggets spark plugs at? 90 or so?

35k miles, so about 56k km (for the 2.0 engine at least)

[Kay15]

Can anyone suggest the type of spark plugs we should use for a 2L 4 C. OEM? NGK? BOSCH?

[naemcivic]

well, depending on your tune. IMO, BOSCH OEM plugs will do just fine.

[eaniemeanie]

I thought the OEM were bosch or NGK? They're switching from one to the other according to the dealer, I can't remember which was switched.

[Kay15]

I have the APR Stage 2. I am looking at NGK Iridium Laser cut or BOSCH. You guys tell me =) ?

[userbbc]

Called a local dealer and they stated the OEM's were NGK. However, seems like I didn't get the correct part number. Any info on the oem NGK part number? For some reason can't seem to find this information anywhere.

[naemcivic]

B8 A4 2.0T Audi part # is 06H-905-601A the # on the plug itself is PFR7S8EG and this is a NGK plug.

[userbbc]

thanks for the part numbers...ordered from sunsetaudi.

One thing, anti-seize - any point in sourcing the copper based compounds vs. the generic aluminum/copper/graphite permatex "advanced formula" found at your local pepboys?

[userbbc]

Found this DIY video on youtube: http://www.youtube.com/watch?v=eN-XW2gqd_E
Was still a little unsure of how the wire harness tabs work but the video makes a little more sense out of it.

As well, emailed NGK and they stated they advised against using any anti-seize:
"With NGK plugs we do not recommend using anti-seize. The zinc coating used on our plugs is all that's needed to prevent corrosion and plug seizure. Just install the plugs dry and you'll be good to go."

[eaniemeanie]

Changed mine on Thursday night. Piece of cake!

[naemcivic]

^^how does your old plugs look like. would you mind snapping a quick photo or 2. just for a comparison?

I want you to know I had to dig through todays oil change on the Pathfinder to find the plugs (they were only underneath a couple paper towels...)

I was having rough idle in the mornings and now the car is much much smoother. I'm guessing I fouled up a plug when my intake blew...

Thanx for sharing the pix. Yeah, I remember when your intake manifold gave away. Indeed, your plugs looked fouled. Looked like it ran abit rich.

Yeah I'm not sure aboutthe lean theory. I do know that in the mornings it idled like a crap box abut after the engine heated up it was better. The plugs were toast for that reason. I would expect to change them every 35K miles.

[userbbc]

"successful" change on my end as well. Though still, was a real pain detaching the wiring harness. Like the guy who made that first DIY i linked to, I ended up breaking one of the clips. Basically spent about 30 minutes getting the wiring harness off and about 15 minutes actually changing the plugs. Need to buy a 90degree pick for next time.

One thing to note, like eaniemeanie, I pulled out Bosch plugs. But the oems that I ordered and installed were NGK's. No noticeable difference on my part as of yet. In fact, no noticeable difference period after changing out the plugs so far. A bit disappointed given the effort spent in detaching that wire harness.

Yeah but better to have no differentce than some. I was running pretty rough for a while....

When I first inquired about plugs (when I was going to do my 55K, but then finding out the dealer replaced them at 35K) Sunset Audi told me that the dealer OEM was switching from Bosch to NGK.

[UmIsThisThingOn]

Did anyone replace their coil packs when replacing the plugs?
Just curious if I should go ahead and order them @ the same time as the plugs.

Most vendors will tell you to do both, but that's salesman speak.....
Where are you buying em?

Are they cracked? Why spend $100 for no reason?

I figured it was just a sales thing. I usually buy my Maintenance stuff from ECS.

Nope - not cracked. Good point.
.
Just plugs it is then.

I'm on my second set of plugs and they are fine. i expect to replace those on the next oil change(95K). My coils look fine. Never trust a person who makes money the more you spend on "maintaining" your car.

[MYFASTA4]

that diy is really close, the only difference that i can tell is that we only have 1 screw holding the conectors to the coils

Awesome pics, Thanks for posting. This will make it alot easier for me. I will be doing this very soon.

[linet90]

Thanks for the pics MYFASTA4, so from them based on the coil packs they need to be replaced. Is there a regular maintenance mileage that they should be changed at?
Based on ECS is their STI packs any better then factory? They also have a tool to remove them is it necessary?

http://www.ecstuning.com/Audi-B8_A4-Quattro-2.0T/Maintenance/Engine/Ignition/

Thanks in advance

[MYFASTA4]

I didn't get the tool just take your time taking them off , maintenance schedule doesn't say but I might replacement at 70 or 100 miles

[linet90]

Sounds good I am ways away from that. So how about those E3 spark plugs?

[MYFASTA4]

Not e3 , idle is smoother :-)

[linet90]

Not e3 , idle is smoother :-)

? please explain

[k9lovr]

Thanks all who have contributed to this thread...very helpful I did mine last night and they were a piece of cake...after 34k they had pretty good amount of use....

I just changed my plugs out at 28k and they looked the same. Oh, and for those who are still unsure of the factory plugs, I pulled out NGK and replaced them with Bosch Laser Iridiums. No difference really. It idles a little smoother but I also did my oil change at the same time so I'm hoping for a little improvement in my Hp as well as MPG's.

[pandacover]

any more detailed pics？

[wabbit23]

Okay so I've been on the Bosch plugs for a couple days now. It feels as if I'm missing some hp. It also seems as if the idle has gotten progressively worse.

[Sonicss]

pulled mine today at 35,500 and they looked the same as above. However, they weren't NGK's. I had bosch from the factory. Idles much better now and saved $600 doing it myself. Thanks for the DIY!

[ljnaum26]

I just ordered these, are they the correct part #?

Are these NGK's correct as OEM replacements from Amazon?

Take a look here for the newest updated VW/Audi sparkplug manufacturer #....

Got mine from genuineaudiparts.com
They are good people out of San Diego that have honest reasonable prices.

Just changed my plugs and when I started the car up it threw the trinity EPS / TPMS / Parking break faults. I will have to scan to see whats wrong. Although car is idling smoothly and had no issues backing out of the garage. We'll see I guess...

EDIT:

For those who may be as dumb as I am... MAKE SURE TO PLUG THE MAF SENSOR BACK IN AFTER FINISHING THE SPARK PLUGS [o_o][>_<]

[Highlander1010]

So based on the WordPrint above, I guess it is these at Amazon.com

Good price at 4 for about $50.

HaHAHA, you sure are dumb. oh wait, I did the exact same thing on the 11th... nm.

Edit:
Not really sure why those were the faults that came up. I think I hit the parking brake like three times before I realized I left the MAF unplugged.

[jordancl]

Those three come up together when something that doesn't have a light of its own goes wrong. Every time they've popped together I've never had any issue with any of the individual items.

I had to vag-com to figure it out, so congrats to you for figuring it out yourself lol

Nice job!! Did yo apply Anti-Seize Lubricant to the spark plug? and what is the torque you use? I saw they use 30 nm for B7, but I am not sure that is the right number for our B8

Thanks

[userbbc]

From emailing NGK, they don't recommend anti-seize on their products (i think i posted this earlier in this thread)
As well, the audi dealership I asked still states 30nm (22lb/ft) on new plug installs.
However, eurocode did post a recommendation for torquing a little higher to around 26-28lb/ft if you're reinstalling the plugs.

Thanks,

How about the dielectric grease. Is that necessary? I will start to replace my own and really want to make sure everything is right.

[userbbc]

not sure if dieelectric is particularly necessary but I do add it to the ceramic portion of the plugs. Supposedly it will keep moisture out of your coil packs and may make removal of the coil packs a bit easier on your next change.

[TCHUN003]

Have any of you guys tried NGK BKR7E's or Bosch FR5DTC's? You have to change them every oil change (5k miles) since they are copper, but they are one heat range cooler and should be a huge improvement if you guys are stage 1 or 2 and running high boost. I might try this out next week. (BTW they only cost $10-18 for a set of 4)

[Highlander1010]

My idle is smoother. I'm adding a DIY for the B8 in the tech.
