What’s the difference on these HR Denso plugs?

Hi,

Quick question, apart from the price, what’s the difference between these two Denso plugs for the HR engine? 
 

Manual shows FXE22HR11, Denso catalogue lists them and Denso iridium TT IXEH22T

 

Car currently has the TT ones fitted, just curious if to swap them out for the originals or go with the same again?

I just plumbed the question into CoPilot (I'm playing around with it never used it before) 

 

 

Which Should You Choose?

• FXE22HR11 is a direct OE long-life iridium plug—reliable, designed for hybrid VQ series engines.
• IXEH22TT delivers advanced twin‑tip ignition technology, potentially boosting throttle response, torque, and fuel efficiency, while also maintaining high durability.
• Practical rule: FXE22HR11 sticks more strictly to OE specs; IXEH22TT offers an upgrade in combustion performance without changing fitment or heat range.

 

Pretty cool eh?

That’s quite a detailed comparison and helps a lot thanks
