Plugz & Leads

I'm not sure about change intervals, probably check every 6 mths just in case u come across something. I've been told to use only NGK plugs(always check the gapping). Not sure about leads, ask at any reputable parts store, I haven't changed mine yet, still in good nick.:thumbsup:

The best plugs you can get are NGK Iridium IX's which are about $21.90 each. The best leads you can get are Magnecore 10mm but most stores like Repco will just tell you Top Gun 10mm which retail at around $240.

Also with the plugs, you should change NGK Iridium IX plugs around every 80,000km's. Every plug is different, its just a matter of checking out the lifespan of the particular plugs you buy.

lol the reason why we say Top Gun 10mm is because thats really the only brand we stock (other than shitty champion and not so far off repco leads) they are great long lasting, powerful leads but like NGK there is always a better brand out there, but will do the job. (if you find somethin you like, check if rocket industrieshttp://www.rocketindustries.com.au/catalogue_brands.php supply that brand. if they do, repco can order it in for)

NGK are one of the best brand spark plugs you can get, they deliver better performance, fuel economy and longer life span than other plugs. Champion are **** (plain and simple) for example if you tighten them (when installin them) you can crack it alot easier.

As far as changing plugs, change them when they start to look bad. Like if they look kinda burnt or have a white powder look on the electrode. For brands I recommend Bosch. Both plugs and leads. Reasonably priced and never had a set fail on me in 8 years. But I have had a set of GM leads fail and no name 'heavy duty leads fail.

I change my plug's religiously every 10000km, i just use the platinum **** NGK's, even on my old SS which churned almost 300rwkw they were fine, as for lead's i wouldn't reccomend any commercial brand's. I used custom lead's by a guy in geelong, cost me almost $400 but you could feel the difference, i sold that car without those lead's for obvious reason's.

I use Bosch spark plugs and genuine lead sets in all my customers cars. I find the range of spark plugs is good and havent had a problem with any of them and genuine leads so the cars look original fitment when they leave the shop.

For standard spark plugs, the change interval is 20,000km's. But as I said earlier, brands like Bosch and NGK have plugs that range around 80,000km and some are meant to last even longer.

i just put some Eagle Performance leads (9mm) on mine and it made a decent noticeable difference
