as5606 Posted July 2, 2002 Share Posted July 2, 2002 I am just going to order some HKS Iridium plugs for my J-Spec Twin Turbo and wondered if anyone knows the part number. I have been onto the HKSUSA.com site and found out that they say it is a 5408-535i I need although don't know if there cars are the same as the J-Spec ones. The site i am buying them from only uses part numbers. Cheers Quote Link to comment Share on other sites More sharing options...
Need4Speed Posted July 2, 2002 Share Posted July 2, 2002 You can get these plugs in the UK over the counter. Beware of importing to save money and then getting hit for Duty & VAT. Quote Link to comment Share on other sites More sharing options...
Nic Posted July 2, 2002 Share Posted July 2, 2002 Try: http://www.hkseurope.com/ Are you running standard boost? If you are then the S35i should be okay, if you are running higher boosts then go for the S40i or even the S45i. Quote Link to comment Share on other sites More sharing options...
Syed Shah Posted July 2, 2002 Share Posted July 2, 2002 Why not save the cash and just get NGKs, they are just as good, if not better, just without the mark-up of HKS plugs. Most people on this site including the most modded cars are fine on NGKs. Quote Link to comment Share on other sites More sharing options...
eyefi Posted July 2, 2002 Share Posted July 2, 2002 yep, the ngk's r very good. ive just looked into this stuff myself and basicaly found that the iridium plugs offer a very very slight performance enhancement over standard copper elements for the first 5 - 10k miles of their life, then after that r really no better. they do last something like 30k miles though, its just that u could have bought about 20 sets of ngks in that time and been running on a fresher plug for longer. my opinion is for the cost the performance benefit is negligable, spend the saving on petrol or something. ps there r 3 different types, all with dif specs check out the denso site (they make them and hks sell them) http://www.denso.co.jp/PLUG/iridium-e/index.html Quote Link to comment Share on other sites More sharing options...

Mark Ayling Posted July 4, 2002 Share Posted July 4, 2002 I paid about £100 for a set of "Blitz Iridum Spec" plugs a while back, only to find that when I took them out of their indiviual "Blitz" boxes they were just NGK plugs anyway ...a lesson learned there!

Mark Ayling Posted July 4, 2002 Share Posted July 4, 2002 Don't know what the model no. is but someone once told me that NGK do make plugs which are repackaged as Blitz and other brand names.... Quote Link to comment Share on other sites More sharing options...
