I guess as long as its healthier for the engine then changing them is good regardless of hardly any difference to performance. I changed my air filter last week, got a K&N panel filter but in all honesty I haven't noticed any difference since changing it. So tomorrow its going to be, change spark plugs, top up the oil, get out the bloody reverse bulb I managed to drop inside the actual rear light, debadge the VVTI and replace with TRD (which hopefully won't look tacky)

I got these ones, recommended by one of the members here. http://cgi.ebay.co.u...e=STRK:MEWNX:IT Not sure when they were last changed but I'll take a picture of the old ones so you can see. What kind of difference would I expected?

Ahh thats great, thanks for your help Dave! I'll try it out tomorrow morning and let you know how I get one. Hope the new spark plugs make a noticeable difference...but doubt they will

I'm going to give it a shot tomorrow morning if it isn't raining! Are the coil packs hard to remove? I don't even know what they are but hey I'll learn from this.

I received some ngk spark plugs yesterday and I'm going to fit them today after work. Never tried it before but I'm going to give it a shot anyway. It's pretty straight forward though right? And once they're changed, is it advised to reset the ecu?

I recognized the word but searched it anyway, came up with "replicas" and then I had a look on google images...haha you got me. Yeah I always come on here and ask stuff but the manual is only under my bed so its probably easier just to pick that up and have a read. Can't remember the last time I opened a book of any sort. I'm not too fussed if its an additional extra, just wasn't sure if I was missing a crucial part which might effect any of my performance. Thanks by the way

Finally! haha thank you, I'm not sure what that is but will have a look into it Oh...its a joke haha...I reckon I need to learn more about cars

As long as everyone else has it missing too then not a problem, but I'm sure I've seen that socket being used for something so I wasn't sure if I was missing something out. Thanks for the info
