XUH22TT Hyundai i20 / i30/ ix20, Kia Ceed / Cerato / Venga, Smart Fortwo LPG and CNG converted cars The ultimate spark plug to use in an LPG engine is the Iridium TT which meets all standard requirements. In the lower cost segment, Nickel TT is the perfect alternative for LPG engines in the place of Nickel, the original fitment for petrol engines. Igniting the air / fuel mixture for both liquid petroleum gas (LPG) and compressed natural gas (CNG) is even more difficult than with engines fuelled by petrol / gasoline. The increased difficulty is because LPG and CNG are injected as a gas whereas petrol / gasoline is injected in a liquid form. Gasses require a higher ionization voltage to create the spark than liquids. The gas also occupies more space than a liquid, so there is less space for fresh air inside the combustion chamber; this reduces the amount of air / fuel molecules around the electrodes. As a result, there is a higher chance of misfire. The higher voltage requirement to ignite LPG / CNG places a higher load on the ignition coil and on the spark plug. Therefore, in many cases, a spark plug with a smaller gap is chosen to reduce the voltage requirement, but the smaller gap then reduces ignition performance. An alternative method of reducing the loads on the coils and spark plugs is to use spark plugs with fine electrodes such as the DENSO range of iridium spark plugs that require lower voltages and therefore allow larger gaps to be retained. In some applications, such as turbocharged engines, the gap may need to be reduced to 0.8 mm. LPG and CNG burn at a higher temperature than petrol / gasoline, which results in larger changes in electrode temperature during the different engine cycles. These larger temperature fluctuations reduce the service life of a spark plug by around 20 - 30%; upgrading the spark plugs to long life iridium spark plugs will improve the life of the spark plug thus reducing overall costs. 3 Spark Plugs TT Application Tables NiTT IrTT NiTT IrTT LTR KW LTR KW ALFA ROMEO CHEVROLET (Continued) 75 (85-92) 1.8 85/85/95 `88-`92 W22TT - AVEO (05-) 1.4 69/74 `06-`07 K20TT IK20TT MITO (08-) 1.4 51/57/58/70/77 `08- XU22TT - AVEO (11-) 1.2 51/63 `11- K20TT IK20TT AUDI CRUZE (09-) F16D4; LDE 1.6 80/82/83/86/89/91 `09- K20TT IK20TT 80 (78-86) 1.6 51/55 `78-`86 W20TT IW20TT KALOS (05-) 1.2 53 `05- W16TT IW16TT 80 (78-86) 1.8 65/66/68 `83-`86 W20TT IW20TT KALOS (05-) 1.4 16V 69 `05- K20TT IK20TT 80 (86-91) 1.8 S 65/66/83 `86-`91 W20TT IW20TT LACETTI (05-) 1.4 70 `05- K20TT IK20TT 80 (91-96) 2.0 66/85 `91-`96 W20TT IW20TT LACETTI (05-) 1.6 80 `05-`09 K20TT IK20TT 100 (90-94) 2.0 74/85 `90-`94 W20TT IW20TT MATIZ (05-) 0.8 38 `05- Q16TT IQ16TT 100 (90-94) 2.3 E 98 `90-`94 W20TT IW20TT MATIZ (05-) 1.0 47/48/49 `05- Q16TT IQ16TT A2 (00-05) 1.4 55 `00-`05 K20TT IK20TT NUBIRA (05-) 1.6 80 `05- K20TT IK20TT A3 (96-03) 1.6 74/75/81 `96-`03 K20TT IK20TT SPARK (05-) 0.8 37 `05- W16TT IW16TT A3 (96-03) 1.8 92 `96-`03 K20TT IK20TT SPARK (10-) 1.0 50 `10- XU22TT - A3 (96-03) 1.8 T 110/132 `96-`03 - IK20TT SPARK (10-) 1.2 60 `10- XU22TT - A3 (03-13) 1.6 75/85 `03-`10 K20TT IK20TT NEON (99-) 2.0 16V 97/98/110 `99-`06 K20TT IK20TT A3 (03-13) BLY; BMB; BVZ 2.0 FSI 110 `03-`08 K20TT IK20TT PT CRUISER (00-10) 2.0 100/104 `00-`10 - ITL16TT A4 (94-01) 1.6 74/75 `94-`01 K20TT IK20TT VOYAGER (95-01) 2.4 i 111 `95-`01 K16TT IK16TT A4 (94-01) 1.8 85/92/95 `95-`01 K20TT IK20TT VOYAGER (95-01) 3.3 i 116 `95-`96 W16TT IW16TT A4 (94-01) 1.8 T 110/132 `95-`01 - IK20TT VOYAGER (95-01) 3.3 i 116 `96-`01 W20TT IW20TT A4 (94-01) 2.6 110 `95-`01 K20TT IK20TT VOYAGER (00-08) 3.3 128 `00-`08 - ITL16TT A4 (00-04) 1.6 75 `00-`04 K20TT IK20TT CITROËN A4 (00-04) 1.8 T 110/120/125/140 `01-`04 - IK20TT 2 CV (63-90) 0.6 18/20/21 `70-`85 WF20TT - A4 (00-04) 2.0 96 `00-`04 K16TT IK16TT AX (86-98) CDY; CDZ 1.0 33/37 `86-`98 K20TT IK20TT A4 (04-08) 1.6 75 `04-`08 K20TT IK20TT AX (86-98) 1.1 40/44 `86-`97 K20TT IK20TT A4 (04-08) 1.8 T 120 `04-`08 - IK20TT BERLINGO (96-) 1.4 48/55 `96- K20TT IK20TT A4 (04-08) 2.0 96 `04-`08 K16TT IK16TT BERLINGO (96-) 1.6 16V 80/81 `00- KH16TT IKH16TT A4 Conv.
