I would get the NGK Iridiums.

 

I have Iridium IX already. Just wanted to know why he went with the Platinum Lasers and why 1 step colder. Curious to his opinion on it

 

plugs are great, the laser platinums are OEM. one step colder is acutally recommended for even stock G's in a year round warm climate or if ur usually on high RPMs. old boy from Technosquare recommended the LP of IR, say's the VQ responds better to LP.

 

Hrmm. I'll have to go with those next time around and see if I notice a difference.

One step colder bad in cold environments??

 

Read post 3 about platinum.

1st, i only put 91 in my car.... 2nd, he's only speeking in gennerallities about platinum it's self in relation to ignition. my point being, generally speaking using a cold air intake should always get you gains in power BUT on the VQ, no. i trust real word over theory. i'm using platinum w/no problems, so are all the stock Gs & Zs, even the people putting in 87.

 

Since we are talking about the ignition system this will greatly increase spark and actually gain wheel horse power. There is a guy on my350z who saw 30 more wheel horse power after he added this.

Is this BS? I mean really...

 

^^^ funny, I was just re-researching that system earlier tonight… I looked into it a yr or 2 ago (or 3) and wasn’t convinced it was worth considering… 30 rwhp is highly suspect. I simply do not believe just an ignition amplifier will give those gains. And if it did, there would be boatloads of us using it with tons of dyno charts.

I remember reading a post by Q45tech that was quite logical – I could never quote it, but it’s a good read and one of the many things that had me ignore the mod originally.

 

damn 30 hp?? are you serious. how come no one has tried this on G's. even if its like 15-20, its still worth it for the price

 

I believe that about as much as a certain shop showing a gain of 5whp+ with a throttle body spacer The ignition system on these cars is more than powerful enough to handle even the most demanding and powerful setups.

 

Seriously man, you're getting to obsessed with every possible NA mod available for these cars. The TB spacer was proof of that. Don't do it

 

yea thts true, im getting obsessed with every NA power mod lol. i need to stop. i might do a before and after with the spacer

 

i have the DLI II, not a power adder. what it does do is keep the spark strong at high speed. Nissan designed the spark to die out to slow you down, like non-100% e-throttle. you can really feel the difference at around 70mph+. it just continues to pull, well passed 100mph. combined w/100% throttle post-reflash, it's a great time. in short, keeps ur spark at optimal levels, that's what made it worth it for me. as for the guy posting the BIG gains, my guess is he was just fixing a BIG loss w/the system.

 

Dave B requires proof before trying and then advocating something. But when he does, he will post pics, dyno and/or track times to back up what he supports.

Some here have all the mods in the world but no dyno support. Not to say what they recommend is false/true, just that there could be better supporting data.
