jerry3167 Posted April 5, 2009 Posted April 5, 2009 Just wondered if these are the CORRECT Denso Spark Plugs? Denso Iridium Power Spark Plug IKH16 What sort of price are they? Jerry Quote
Stew Posted April 5, 2009 Posted April 5, 2009 Try Opie Oils. A quick search churned up there name for doing specials. Quote
jerry3167 Posted April 6, 2009 Author Posted April 6, 2009 Did contact OPIE, and Guy has them at a cracking price!! Jerry Quote
Andy Posted April 6, 2009 Posted April 6, 2009 Good shout on Opie, got mine from there last week. Quote
Stew Posted April 6, 2009 Posted April 6, 2009 Wow. A useful post from me.... that's a rare thing! Quote
Renegade Posted April 7, 2009 Posted April 7, 2009 Looking at changing mine myself.It looks fiddly. Does the strut brace need to come off, and if so is there a special way of tensioning it when you replace it. It looks like the air intake pipes need removing too. Quote
jerry3167 Posted April 7, 2009 Author Posted April 7, 2009 OMG..just to change the Plugs WTF?? Thats one way the STEALERS get you to go to them, they know that you wont be arsed to do it yourself!! Are oil changes easy to do on a Z, or another hassle? Jerry Quote
BulletMagnet Posted April 7, 2009 Posted April 7, 2009 oil changes are easy. but did go to my local garage and put her on a lift, removed the plastic covers underneath and the oil filter is really easy to access. Quote
jerry3167 Posted April 7, 2009 Author Posted April 7, 2009 Phewwww! Glad to hear that! I change my oil per 3K miles so good news!! Cheers Jerry Quote
Renegade Posted April 7, 2009 Posted April 7, 2009 I found a nice write up here. viewtopic.php?f=35&t=4021&p=39148&hilit=+change+plugs+how+easy#p39148 Can anyone answer my question about replacing the strut brace and tensioning it. Quote
H5 Posted April 8, 2009 Posted April 8, 2009 The strut brace can be loosened towards the passenger side and then simply undo the 3 bolts and one nut each side to take it off. Once it is off the car will settle ever so slightly so when you put it back on it may not be as tight / be tighter. Once it is back on I would take the car down the road and then check if there is still tension in it. As long as it is bracing the struts, you're fine. (technically you're fine without one at all) Quote

jerry3167 Posted April 8, 2009 Author Posted April 8, 2009 Got my DENSOs from Oilman (Guy) Many thanks for a fast and courteous service!! Cheers Jerry Quote
H5 Posted April 8, 2009 Posted April 8, 2009 Just ordered mine from there too, taken advantage of the Easter discount too! Plugs are £15 each from Nissan. These are less than £40 for 6 through Opie at the moment. Quote
DavidS14 Posted April 8, 2009 Posted April 8, 2009 Is there a reason for using Denso Iridiums ? A lot of us on the SXOC use NGK Iridium's instead. The difference being that the electrode on the Denso's has a ∅ 0.4mm where the NGK's are ∅ 0.6mm so they seem to stand up to occasional det better (and the NGK's are cheaper ) . Just looked at the spec for the Denso Iridium Long Life series and the have the ∅ 0.7mm electrode but are £12 each for my SR20DET where the NGK's are £6 Quote
jerry3167 Posted April 8, 2009 Author Posted April 8, 2009 The DENSOs I got have the 0.4mm electrode -Melting point Iridium 2454 degrees / Platinum 1769. Basically, the smaller the electrode, the more concentrated the electric potential at the electrode. The stronger the electric field, the lower the required voltage. As a result, combustion is good for all types of driving, engines starts easily, and acceleration improves. Jerry Quote
DavidS14 Posted April 8, 2009 Posted April 8, 2009 I understand the reasons for Ir over Pt and Cu electrodes but want to know if there was anything special about the Denso's that made them a better choice than other Ir's. Just stocking up on 350 info for the future Quote
jerry3167 Posted April 8, 2009 Author Posted April 8, 2009 Personal choice really, heard good things about Denso, even though I always used NGKs in my Type-R, that and the Densos are a tad cheaper. Quote
Rosssco Posted April 16, 2009 Posted April 16, 2009 Just ordered mine from there too, taken advantage of the Easter discount too! Plugs are £15 each from Nissan. These are less than £40 for 6 through Opie at the moment. Are they? £53.44 on the website currently, but I guess the easter sale is over, and thats still a good price really... Quote
H5 Posted April 17, 2009 Posted April 17, 2009 At the time with the discount they were. Still a much better price than Nissan! Quote
Renegade Posted April 17, 2009 Posted April 17, 2009 I got some from opie too Does anyone know if these need gapping,or even what it should be to check them ? Forget that its 1.1mm got it from opie site. Quote
sunset350z Posted April 17, 2009 Posted April 17, 2009 I bought a set of the denso iridiums from Opie oils last year at Japfest Fitted them myself, which isn't as difficult as you may think. I was advised by some people to take the plenum chamber and lower collector off completely, but unless you like the extra work, or you are adding a spacer at the same time, there is absolutely no need. Take the strut brace and air intake pipe off to start with. Then move the wiring looms on both sides running above the coil packs out of the way. Undo the bolts holding the coil packs in place, and pull them out of the way. Then with a suitable extension and plug socket on your ratchet undo and remove the old spark plugs and replace with the new ones. Do not overtighten A simple nip up is all you need to do. Refit the coil packs and wiring, then the air intake and strut brace, and Bobs your uncle Quote
Renegade Posted April 18, 2009 Posted April 18, 2009 Will one of these be long enough ? http://www.halfords.com/webapp/wcs/stor ... yId_165469 I have one in the garage from my 200 sx days Quote
sunset350z Posted April 18, 2009 Posted April 18, 2009 That should be long enough, but i used a plug socket on an extension bar and ratchet, as you may find you need to alter the angle to get at the spark plug. Have one handy just in case. I bought a socket set similar to http://www.halfords.com/webapp/wcs/stor ... =ClickInfo from Halfords and its been a god send for working on the zed Quote
