i think IU 24 is a cold spark plug..but IU 27 is much colder

DENSO IU24 = good for street/everyday use
DENSO IU27 = good for circuit/drag race use (high rpm)

 

[tofujelly]

which is better?

Denso or NGK brand?

i bought NGK CR9EIX last IR bike fest

but i haven't tried it yet coz my cousin borrowed it for his project (he will replace it for sure) :evil: hehehe

is there anyone who can give some feedback about this spark plug?

IUF series
IUF22
･ 10mm dia. X L12.7mm length short reach type.
･ Using the high heat resistance of the iridium, the spark position is extended 0.4mm compared to standard types (1.6 → 2.0mm)
･ Harnessing the low required voltage of the 0.4mm dia. iridium, the spark gap is wider than in normal types (0.7 → 0.8mm). Ignitability is greatly increased.

[the_one]

what can you suggest for everyday-short-distance-high-rpm use

recommeded for SNIPER/X1R..

DENSO U24EPR9
DENSO IRIDIUM IU24
DENSO RACING IU01

 

[jamskie]

using IU 24 here..nice performance

 

[rhoitol]

the stock SP of the sniper or x1r is longer than the Denso IU24 when i compare the length, but why?

is there any side effect?

tried to use IU27 for everyday use coz my brother's been using my bike at very high rpm..guess it's good but my mechanic adviced to go back to ordinary plugs...dunno y...
