Need to change the plugs and air filter in New Beetle 1.6 engine (same one as in Golf and A3 - 105BHP).
Is there any benefit to getting higher performance sparks - better performance or economy, or do they just last longer - or just cost more ?!
Ditto high performance air filters - any use spending more on them ?

P or PP at the end of the part number usually designates one or two platinun plated electrodes(used for durability). C or CC is the same for copper plated but won't last as long.Air filters-the manufacturers are best.
|
Been searching the web a bit in the meantime !
Seems Iridium plugs are the latest thing - anyone used them ?!

C and CC certainly mean copper, but I believe it means copper cored electrode(s), for better heat transfer, rather than copper coated.

Platinum and Iridium last much longer (less spark erosion) so gap is maintained over 50-60k miles. Tip is usually smaller too, meaning that spark strikes at a lower HT voltage - less chance of misfiring under adverse combustion conditions.

Thanks for the advice - will let you know if the car goes any better !
Found a good website - www.spark-plugs.co.uk/ , who also promptly answered 2 e-mails I sent them - prices seem pretty good, too !
