spark plugs ---help!!!

[sms]

i have just taken out the spark plugs to find the ones i got today are not as long. do the fsi and tfsi have different length spark plugs or can these shorter ones be used with not much difference the ones from mr fish say VW AG Bosch on them but its because they are shorter that i havent put them in yet.

cheers

Have you checked the electrode gaps too?

Potentially the engine will loose a bit of efficency, so i would say no, dont use them.

[sms]

the gaps look fine to the eye, not personally got any feelers in there yet.

[Tech1e]

Do you know the part number for the new plug?

Whats you engine code?

[sebulbus]

I think the shorter plugs mean less compression because of the added space in the combustion chamber.

But I wouldn't use them anyway, there are a lot of parameters in a spark plug, and they may not be a match either.

the plugs are from makefish, they were out of his car 2.0tfsi mine is a 2.0 fsi dont know off hand what my engine code is.

They are the wrong plugs don,t use them.

[sms]

no probs, i took one look at the size of them and decided to halt as alarm bells were ringing in my head, so i thought i would ask the briskoda family. looks like im off to halfrauds tomorrow then.

The heat range of a turbo plug will be different to a normally aspirated car.

[vRSLen]

Why would you need to change the plugs at such short mileage?

[sms]

the car is on 20k and the service schedule says 40k which im not happy about. the plugs were out of makefish's car within 1k of him having them (as he upgraded to cooler plugs).

[Tech1e]

Longlife plugs as fitted to the FSi last longer than 40k which has always been the interval for plugs on VAG cars for years.

[sms]

so by changing the plugs i wont actually benefit then?

[Yeti_Man]

so by changing the plugs i wont actually benefit then?

VAG's recommendations will be based on ££££££ of development and testing and they arent going to say a component will last longer than it should as they would surely loose out at service time and be open for the possibility of higher warranty claims.

Nope.

While we're at it, what is the spark plug part # for 1.6 FSI (BLF) fab. date Nov '05, please?

[TeflonTom]

I think the shorter plugs mean less compression because of the added space in the combustion chamber.

:rofl:

shorter plugs = hotter

typically plugs from a turbo car have a bigger gap too

[sms]

thanks all, i now have a set of 2.0tfsi spark plugs with about 1k miles on them for sale if anyone is interested

[sebulbus]

Bump. Does anybody have the part no for the 1.6 FSI spark plugs? Or can suggest the OEM maker so I can order the same from a 3rd party supplier?

Are these easy to replace yourself?

[chavdarlk]

1.6 FSI do not use usual spark plugs. It uses coilpacks, combining spark plug and coil into one package.

It costs about 40 Euro for piece, as I can remember.

[sebulbus]

Funny enough I've been quoted spark plugs from 4 different makers earlier today and didn't know which one to choose from. All ranged from 10 to 14 euros a piece, so a grand total of 40 to 56 euros plus labour.

Other sources on the net show the 1.6 FSI uses regular spark plugs as well. The NGK catalog being one, IIRC.

Bump.

The Octi uses NGK ZFR6S-Q plugs that come pre-gapped and have 4 ground electrodes a piece.

To replace:

Remove engine cover by removing the air duct near-right, 2 sensors far right. Take advantage of this and change the air filter, it's just 6 more screws to undo.

With the cover off the coil packs and wires are visible. With a flat blade screw driver release all the tabs holding the wires in place so you have more freedom to move.

Gently wedge something beneath the coil packs and lift out one by one.

Replace spark plug torqueing each one accordingly, or tightening 1/2 turn after snug. Replace engine cover and drive car.

I didn't manage to unscrew the plugs in mine today as they are VERY tight, and will give it another go in the morning, dead cold which should hopefully help. I broke 3 spark plug wrenches today, so I am going to get a bit for the ratchet and extension arm tomorrow and try again.

I'd give this job a 2/5 difficulty rating. Very little tools necessary and no crawling under car, unless you are sloppy and drop the bolts. Something you can very easily do in 30 minutes in the parking lot.

Hope somebody will find this useful.

[sebulbus]

Forgot to update this. After a night's soak in penetrating fluid and the engine cold over night (4-5C outside nowadays) I managed to undo them.

There is some soot deposit forming on the tapered edge, so changing them earlier if you're mostly doing city driving is a good idea, otherwise you might end up cracking them in the cam cover.

Just to clarify, the 1.6FSi definitely does use spark plugs because I changed them myself at 40k for some Denso aftermarket ones.
