V36 Vq35hr Spark Plugs?

[ahxching]

Hey guys,

I have a 2006 Skyline V36 Type SP

- Just wondering what spark plugs people have used for these cars and any feedback?

- Heard that NGK is good

- Where to buy?

Any inputs would be great!

[Ben C34]

Ngk is good.

What do you want to achieve with the spark plugs?.

Daily driver

Any idea on where to buy and code for ones?

Iridium seems to last longer, so prob opt for those

[Rufus007]

Factory OEM for vq35hr are Iridium - Denso FXE22HR11. Got mine from Nissan, they were $34 each though. Maintenance schedule on these is 170,000km but I recommend replacing earlier.

Got told on FB group regarding this query, got told that nissan spark plugs are: PLFR5A-11

Can anyone confirm this is OEM?

Seems to be decently priced aswell

Get yourself a copy of the 2007 g35 service manual - its listed in there.

The plugs you listed are 2 full steps hotter then OEM - Be careful.

I buy lots of things online, one I don't recommend is spark plugs. Received some once knocked up and in bad shape - had to send back.

you don't need to go to Nissan, you can buy the same NGK plug without the nissan packaging.

Just be careful of counterfeit NGKs online.

Went onto the NGK website and found compatible spark plugs for the 350Z VQ35HR (same engine) and they recommended DF7H-11B, repco also recommended the same ones

Found some other link which stated LFR5AIX-11.

Still unsure which ones to purchase

[Rhinorebel]

Once the correct plug is purchased, are they gapped correctly??? Or should I check the plugs coming out and make sure the new ones are the same gap???

[sonicii]

You should never gap iridium or platinum plugs, you will snap off the electrode.. the -11 at the end of the part number specifies a gap of 1.1mm..

[sonicii]

seems NGK recommend a 7 heat rating for the HR engine and a 5 heat rating for the DE engine, so I think the LFR5AIX-11 is probably for the VQ35DE.

[ahxching]

Might just end up buying the ones that were recommended by repco and NGK website - DF7H-11B,

No idea on how to check heat rating and all that....

[Leroy Peterson]

DF7H-11B,

No idea on how to check heat rating and all that....

7 in that code refers to heat range

11 refers to the 1.1mm gap

Bump for this thread.  We have a 3.5L 2007 v36 sedan skyline and looking for spark plugs

DE is regular and HR is direct injection (350z with VQ35HR)

Went to autobahn and there were two options NGK LFR5AIX-11 Irridium @ $25 each lasts 60k and Platinum PLFR5A-11 @ $33 each rated for 100k.  That last plug was to suit 03-07 Nissan 350Z.

Not sure which plug to go for ?

[Ben C34]

Cheaper one.

You will  probably sell the car before you need plugs again. That's what my crystal ball is telling me.

Otherwise the plug is the same gap and heat range . There is absolutely no way you would notice the difference.

HR is not direct injected.

The direct injected engines end with a DD.  for example VQ30DD, VR30DDTT, MR16DDT, etc

The PL and I guess the LF are for the DE engine which hav different plugs to the HR.

If for the HR motor I would be heading towards the DF7H-11B,  myself.
