hey guys

well i got the usual symptoms car misfiring around 3 - 35 -4000 revs and after reading all the possible causes

i thought the easiest one to check would be the plugs

after taking em out i found them to be like this

you never seen someone so happy to find shitty plugs

do you reckon theyve been changed in the last 20000kms?

so whats a good replacement plug?

and im guessing 0.8 gap is the way to go?

some plugs are meant to be changed even later than that.

You should gap them to 0.8,clean them,throw them in and see what happens.

Btw my car has ngk irridiums and they dont miss a beat @ 13psi 185rwkw.They are 22000km old.All they have seen is a clean with a wire brush.

I think the irridiums are quoted to live as long as 90000km.

There are better plugs out there nowadays though.dont ask me what ones.That time will come when i need newwies.

I just use the coppers.

If you've got a fairly stocker car, the irid/platinum arent so bad... but if your playing around with mods and stuff you can foul them at times so coppers workout cheaper in the end... sometimes.

Depends on the car really. I fouled a fuel reg 5000km's into a new set of irid... @ $100 a set, i wasnt gonna waste that again, back to coppers.

I get almost a year out of them, sometimes less

If you look closely you can just make out the track marks along the insulator. I would recommend iraway 7's as they are pre gapped. The beauty of iridiums over coppers is that you can open the gaps up a little more.

Well just a follow up post

i havent changed the plugs since i bought the car a months ago and it seemed fast back then

anyway i changed the plugs today to ngk iridiums gapped to .8

feels like a weapon now hey

it just has power all the way through the revs

would definatly recommend changing plugs if ya car is lacking a bit of power or missin a bit

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
