I am thinking of having a go at doing the spark plugs on my VRS.

I was wondering if anyone could help with a link to a guide and also a link/part number for the correct spark plugs to buy?

I have gone on to eurocarparts and put my reg in and it is coming up with three options. One is NGK Spark PlugPart No.: 408440040 , manufacturer number: 6458

Are these correct?

Last time "I tried my plugs" it all went horribly wrong and cost me nearly a grand !

Surely a garage job who won`t make a costly mistake?

What did you do wrong to cost almost £1k?

The original NGK platinum plugs are PFR7S8EG. That is an NGK part number, Euro car parts will rename them with their part number. There is an Iridium version available too.

I got a set of 4 genuine VAG branded (06H905601A) platinum ones from eBay for £21 inc del, bargain!

The NGK Spark plug part number is PFR7S8EG or VW part number 06H 905 601 A. Also NGK part number code is 1675

Step 1: Remove your engine cover.

Step 2: Disconnect the wiring harness from the coilpacks.

Step 3: Carefully pull the coil packs up off the plugs. Needle nose pliers can be slid in under the edge of the coil pack to help push it up. If you are re-using the coilpacks, pay attention to which cylinder they came from.

Step 4: Using the socket wrench, extension, and spark plug socket… loosen and remove the spark plugs.

Step 5: Get your new spark plug ready. Verify the gap (they should be pre-gapped to 0.030?). Apply a light coat of anti-seize to the threads. (optional)

Step 6: Using the extension and spark plug socket, screw the new plugs until they are hand tight.

Step 7: Tighten the spark plugs until snug. If you’re the anal type, here’s where you break out the torque wrench and tighten to spec (20 Nm).

Step 8: If you’re installing new coilpacks, have them ready.

Step 9: Install the coil packs by pressing them firmly onto the plugs. If you’re re-using the old coil packs, try to put them back on the same cylinder they came from.

Step 10: Reconnect the wiring harness. Press each connector on until it clicks. Refit engine cover and connect MAF sensor

Hope that helps.

Stripped the thread of one of them resulting in the head off on my Zaffi GSi turbo

About £900 if I remember!

Gutted!

To be honest, it happens, but this is the first car i've not yet changed the plugs myself on.

To make life easier I wrap a cable tie into a loop and that fits beneath the coilpacks to give you something to pull on when removing.

I recently changed to two heat range cooler than OEM (iridium 8 series) and the car runs fantastic as a result!

Thank you for that.

i don't suppose you have a guide/tips on how to remove the engine cover do you?

It is a bugger to get off, the worse designed engine cover I have ever had , pull upwards from the back, this link shows you it underneath, the rubber bungs are how it is attached ,(imagine your thumb going in to the bungs ) metal protrusion http://forums.vwvort...ead.php?2547554 if you don't swear now, you will after

Yep the euro car parts numbers you have are correct, i had the same plugs a couple of months ago.<br /><br />If you enter the code oilspill30 @ checkout you get 30% off so the set of 4 will cost £26.56.

Im that scared don`t even like to change my own tax discs now lol

A little tip on fitting new plugs is to initially fit them using a piece of hose pipe.

Push hose onto the plug and then lower into the hole., if you don't have the threads lined up correctly then the hose spins on the plug. As you begin to tighten it. Once your happy threads are good then simply just pull the hose out and finish job with correct tool. I always use a torque wrench for plugs out of habit with having a rover k series!

No need for hosepipe IMO, seems a bit of a faff?

A spark plug wrench with a rubber insert in the socket is just the job for me.

True! For most, however using a spark plug wrench with black rubber insert won't stop crossing threads, because your still turning the plug, if it's slightly out then you have a risk of damaging the threads. Using the hosepipe, then if the threads aren't perfectly lined up when beginning insertion the hose pipe will as I mentioned spin off, therefore not damaging threads costing £900 quid as someone mentioned earlier. I'm just offering a solution to somebody who might be nervous about doing there plugs as not everybody is confident under a bonnet.

What size are these plugs? i.e. What socket size do I need to buy to change the spark plugs in my Octavia VRS 06?
